"Aha" effects in the generation of pictures

The role of creative cognitive reappraisals in positively transforming negative emotions

Recent studies have found the connections between cognitive reappraisals' creativity and their regulatory efficacy. The present study proposed and tested a novel hypothesis on the function of cognitive reappraisals, especially creative ones. That is, whether they could positively alter negative emotional arousal toward unpleasant stimuli. To this end, two questions were investigated: (a) whether the creative reappraisals were more capable than ordinary ones of transforming the negative stimuli (pictures) to be perceived as positive, and (b) whether these two kinds of reappraisals made the "negative-to-positive transformation" through different mechanisms. To answer the first question, we examined the power of the creative and ordinary reappraisals in making the "negative-to-positive transformation" using an indirect and delayed "positive-or-negative" picture-sorting task (Exp. 1, n = 41 with a statistical power of 0.877), or using a direct and immediate subjective rating (Exp. 2, n = 31 with a statistical power of 0.768). To answer the second question, we checked how the factor of creativeness (creative vs. ordinary reappraisal) interacted with the factor of "timing" (simultaneous vs. delayed reappraisal delivery, Exp. 1), or with that of "dose" (one vs. three reappraisal applications; Exp. 2), in making the "negative-to-positive transformation," respectively, and examined if the variation of "timing" or "dose" factors would exert different effects on the creative and ordinary reappraisals' regulatory function. Our results generally proved that creative reappraisal was more capable of making the "negative-to-positive transformation" than the ordinary reappraisal, regardless of the direct and indirect emotion evaluation ratings as well as the variations in the timing and dose of reappraisal delivery. Moreover, we found that these two kinds of reappraisals could show dissociable dose-dependent effects (but not timing-dependent ones), thus partially implying that creative and ordinary reappraisal might make the "negative-to-positive transformation" through fundamentally different processes or mechanisms.

Quantifying the roles of conscious and unconscious processing in insight-related memory effectiveness within standard and creative advertising

To maximize marketing effectiveness, many conscious and unconscious elements are simultaneously employed within campaign advertising. However, little is known about the individual contributions that conscious and unconscious processes make to the cognitive effectiveness of creative advertisements, some of which may also induce insight experiences. To quantify the roles of conscious and unconscious processes in memory effectiveness within commercial advertising, a dual-process, signal-detection technique was adopted to separate the contributions of conscious recollection and unconscious discrimination induced by 80 printed advertisements, among which half were considered standard and the other half creative. A total of 51 participants completed immediate (5 min later) and delayed (3 days later) memory recognition tests. In contrast to standard advertising, creative advertising was found to enhance recognition and to demonstrate advantages in both conscious and unconscious memory, which decreased across the test-time intervals. Further analyses showed that a moment of insight induced by an advertisement, regardless of whether it is standard or creative, can consolidate unconscious memory, whereas advertisements that do not induce insight improve conscious memory. The implications of these findings are discussed.

What makes creative advertisements memorable? The role of insight

Sudden insight is often observed during creative problem solving and studies have suggested that advertisements can likewise evoke an insight experience. To date, however, there is limited empirical evidence on whether advertisements can trigger ideational insight, and, if so, whether such insight plays a role in advertising memorability. This study aimed to explore the insight experience evoked by advertisements and to examine the role of such experimentally-induced insight in predicted memory and metamemory performance. Participants viewed standardized advertising images sequentially, with each image presentation being followed immediately by a second presentation either with or without a brief description of the advertising idea. Next, participants were asked to recall the three most impressive advertisements. Finally, participants were randomly divided to complete either immediate (5 min later) or delayed (3 days later) recognition tests and to provide retrospective confidence judgments (RCJs). Recall of creative advertisements was better than standard advertisements and most of them evoked insight. In addition, recognition accuracy was greater for creative advertisements relative to standard advertisements and metamemory performance as elicited through RCJs was enhanced. Further analyses confirmed the documented importance of insight for memory consolidation. The findings suggest that insight makes advertisements more memorable, especially those that are creative.

Event-related potentials support the mnemonic effect of spontaneous insight solution

The mnemonic effect of insight refers to the situation in which experiencing an "aha" moment when solving problems could improve memory performance for both the question and its solution. The aha experience can be triggered either by external stimuli or by internal solution attempts, namely "induced" or "spontaneous" insight, respectively. Tests of the neural correlates of the insightful memory effect are typically conducted in induced insight paradigms. The neural mechanism of the mnemonic effect of spontaneous insight is unclear. In the present study, the mnemonic effect for spontaneous insight was examined by the event-related potentials (ERPs) technique and behavioral measures. Subjects were required to solve a set of Chinese verbal compound remote-associated tasks (CRA), and performed a recognition test 10 min later. The results showed that the spontaneous insight solution elicited a more negative deflection than did the non-insight solution before the button reaction (- 800 to - 400 ms) in the study phase. In the recognition test phase, items which elicited insight during study were recognized faster, compared with non-insight study items. And spontaneous insight solution elicited a more positive deflection than did non-insight solution in the time window from 400 to 700 ms after onset of the answer. Moreover, brain-behavior correlations revealed a relationship between N400 amplitude during study and later memory performance which revealed a double-dissociation between items solved with and without insight during study. The different predictions for recognition indicate that the encoding of spontaneous insight may differ from that of non-insight, suggesting that different encoding mechanisms may mediate the encoding of items and solutions found by insight versus non-insight.

Feeling the Insight: Uncovering Somatic Markers of the "aha" Experience

Whether internal insight can be recognized by experiencing (somatic feeling) remains an unexplored problem. This study investigated the issue by examining potential somatic markers of the "aha" experience occurring at the moment of sudden insight. Participants were required to solve a set of compound remote associates (CRA) problems and were simultaneously monitored via electrodermal and cardiovascular recordings. The "aha"-related psychological components and somatic markers were determined by contrasting insightful solutions with non-insightful solutions. Results showed that the "aha" experience was an amalgam entailing positive affects and approached cognition accompanied by a greater mean skin conductance response (mSCR) amplitude and a marginally accelerated heart rate than the "no-aha" one. These results confirm and extend findings of the multidimensionality of the "aha" feeling and offer the first direct evidence of somatic markers, particularly an electrodermal signature of an "aha" feeling, which suggests a sudden insight could likely be experienced by individuals' external soma.

The Mnemonic Effects of Novelty and Appropriateness in Creative Chunk Decomposition Tasks

Creativeness has been widely recognized as the ability to generate thoughts that are both novel (new) and appropriate (useful) (Barron, 1955). In this paper, we investigated the mnemonic effects of novelty and appropriateness in chunk decomposition tasks. Studies 1 and 2 utilized classical recognition tasks (explicit memory) and ambiguous word identification tasks (implicit memory) to reveal whether novelty and appropriateness are involved in different mnemonic systems. A 2 (familiarity) × 2 (appropriateness) experimental design was utilized in our experiments, and the four conditions were familiar-appropriate, familiar-inappropriate, novel-appropriate and novel-inappropriate. The results indicated that insight induced by novelty (novel-appropriate condition) has a better performance than other conditions; and further, found an interesting phenomenon of Zeigarnik-like effect which referred to remembering uncompleted tasks better than completed tasks (Zeigarnik, 1927). We further conducted Study 3 to ask participants to recall the encoding process (how the characters had been decomposed in the learning stage), which was more sensitive to Zeigarnik effect and indicated that performance of familiar-appropriate condition (uncompleted tasks) was better than other conditions.

Neural Correlates of Learning from Induced Insight: A Case for Reward-Based Episodic Encoding

Experiencing insight when solving problems can improve memory formation for both the problem and its solution. The underlying neural processes involved in this kind of learning are, however, thus far insufficiently understood. Here, we conceptualized insight as the sudden understanding of a novel relationship between known stimuli that fits into existing knowledge and is accompanied by a positive emotional response. Hence, insight is thought to comprise associative novelty, schema congruency, and intrinsic reward, all of which are separately known to enhance memory performance. We examined the neural correlates of learning from induced insight with functional magnetic resonance imaging (fMRI) using our own version of the compound-remote-associates-task (CRAT) in which each item consists of three clue words and a solution word. (Pseudo-)Solution words were presented after a brief period of problem-solving attempts to induce either sudden comprehension (CRA items) or continued incomprehension (control items) at a specific time point. By comparing processing of the solution words of CRA with control items, we found induced insight to elicit activation of the rostral anterior cingulate cortex/medial prefrontal cortex (rACC/mPFC) and left hippocampus. This pattern of results lends support to the role of schema congruency (rACC/mPFC) and associative novelty (hippocampus) in the processing of induced insight. We propose that (1) the mPFC not only responds to schema-congruent information, but also to the detection of novel schemata, and (2) that the hippocampus responds to a form of associative novelty that is not just a novel constellation of familiar items, but rather comprises a novel meaningful relationship between the items—which was the only difference between our insight and no insight conditions. To investigate episodic long-term memory encoding, we compared CRA items whose solution word was recognized 24 h after encoding to those with forgotten solutions. We found activation in the left striatum and parts of the left amygdala, pointing to a potential role of brain reward circuitry in the encoding of the solution words. We propose that learning from induced insight mainly relies on the amygdala evaluating the internal value (as an affective evaluation) of the suddenly comprehended information, and striatum-dependent reward-based learning.

Generation and the subjective feeling of "aha!" are independently related to learning from insight

It has been proposed that sudden insight into the solutions of problems can enhance long-term memory for those solutions. However, the nature of insight has been operationalized differently across studies. Here, we examined two main aspects of insight problem-solving—the generation of a solution and the subjective “aha!” experience—and experimentally evaluated their respective relationships to long-term memory formation (encoding). Our results suggest that generation (generated solution vs. presented solution) and the “aha!” experience (“aha!” vs. no “aha!”) are independently related to learning from insight, as well as to the emotional response towards understanding the solution during encoding. Moreover, we analyzed the relationship between generation and the “aha!” experience and two different kinds of later memory tests, direct (intentional) and indirect (incidental). Here, we found that the generation effect was larger for indirect testing, reflecting more automatic retrieval processes, while the relationship with the occurrence of an “aha!” experience was somewhat larger for direct testing. Our results suggest that both the generation of a solution and the subjective experience of “aha!” indicate processes that benefit long-term memory formation, though differently. This beneficial effect is possibly due to the intrinsic reward associated with sudden comprehension and the detection of schema-consistency, i.e., that novel information can be easily integrated into existing knowledge.

Aha! experiences leave a mark: facilitated recall of insight solutions

The present study investigates a possible memory advantage for solutions that were reached through insightful problem solving. We hypothesized that insight solutions (with Aha! experience) would be remembered better than noninsight solutions (without Aha! experience). 34 video clips of magic tricks were presented to 50 participants as a novel problem-solving task, asking them to find out how the trick was achieved. Upon discovering the solution, participants had to indicate whether they had experienced insight during the solving process. After a delay of 14 days, a recall of solutions was conducted. Overall, 55 % of previously solved tricks were recalled correctly. Comparing insight and noninsight solutions, 64.4 % of all insight solutions were recalled correctly, whereas only 52.4 % of all noninsight solutions were recalled correctly. We interpret this finding as a facilitating effect of previous insight experiences on the recall of solutions.

Application of the self-generation effect to the learning of Blissymbols by persons presenting with a severe aphasia

This study investigated the application of the self-generation effect to enhance the recognition and retention of Blissymbols in persons with severe aphasia. A 2×2×3 factorial design of two treatment types (self-generation and non-generation) was used to teach two sets of Blissymbols. These were administered during 3 training days, between which were withdrawal periods of 1 day and 7 days. Recognition and retention probes were administered at intervals during the training. ANOVA analysis showed that the self-generation treatment produced no immediate recognition advantage; however, better retention of symbol recognition may have occurred over time. Hence, the potential application of the self-generation effect in enhancing the retention of Blissymbols in persons with severe aphasia may warrant further investigation.

Spatial Mental Representation: Implications for Navigation System Design

Similarities exist in how people process and represent spatial information and in the factors that contribute to disorientation, whether one is moving through airspace, on the ground, or surgically within the body. As such, design principles for presenting spatial information should bear similarities across these domains but also be somewhat specific to each. In this chapter, we review research in spatial cognition and its application to navigation system design for within-vehicle, aviation, and endoscopic navigation systems. Taken together, the research suggests three general principles for navigation system design consideration. First, multimedia displays should present spatial information visually and action and description information verbally. Second, display organizations should meet users' dynamic navigational goals. Third, navigation systems should be adaptable to users' spatial information preferences. Designers of adaptive navigation display technologies can maximize the effectiveness of those technologies by appealing to the basic spatial cognition processes employed by all users while conforming to user's domain-specific requirements.

Representational flexibility and specificity following spatial descriptions of real-world environments

Current theories are mixed with regard to the nature of mental representations following spatial description reading. Whereas some findings argue that individuals' representations are invariant following text-based, map-based, or first-person experience, other studies have suggested that representations can also exhibit considerable flexibility. In the current project we investigated the influences of spatial description perspectives and depictions on the nature of mental representations. In Experiment 1, participants exhibited more flexibility following survey, compared to route, spatial descriptions. With extended study time, though, flexibility following route descriptions increased. In Experiment 2, complementary maps further enhanced flexibility for route-based descriptions. Interestingly, increased exposure to these maps actually reduced flexibility following survey descriptions. These results demonstrate that the nature of our spatial mental representations depends upon a variety of factors; delineating these factors is critical for resolving debates concerning the malleable and invariant characteristics of spatial memory.

TheAhaEffect in Groups and Other Dynamic Learning Contexts

The aha effect is a memory advantage for initially ambiguous stimuli (e.g., "The notes were sour because the seam split.") that are subsequently resolved ("Bagpipe") over stimuli that are comprehensible from the outset (see P M. Auble, J. J. Franks, & S. A. Soraci, 1979; T. W. Wills, S. A. Soraci, R. A. Chechile, & H. A. Taylor, 2000). The authors examined the influence of learning context on the aha effect by manipulating whether generative tasks were completed in a group setting or alone. In Experiment 1, participants in a group context either discussed difficult aha sentences, or overheard the discussion. In Experiments 2 and 3, lone participants were exposed to the sentences, and either spoke their thoughts aloud or thought silently. Participants in a group context did, as predicted, exhibit the aha global deletion of quotation marks effect. Moreover, in all experiments an aha effect was found for the active, speaking condition only. The authors discuss implications for generative learning and collaborative discourse processes.

Neural activity when people solve verbal problems with insight

People sometimes solve problems with a unique process called insight, accompanied by an “Aha!” experience. It has long been unclear whether different cognitive and neural processes lead to insight versus noninsight solutions, or if solutions differ only in subsequent subjective feeling. Recent behavioral studies indicate distinct patterns of performance and suggest differential hemispheric involvement for insight and noninsight solutions. Subjects solved verbal problems, and after each correct solution indicated whether they solved with or without insight. We observed two objective neural correlates of insight. Functional magnetic resonance imaging (Experiment 1) revealed increased activity in the right hemisphere anterior superior temporal gyrus for insight relative to noninsight solutions. The same region was active during initial solving efforts. Scalp electroencephalogram recordings (Experiment 2) revealed a sudden burst of high-frequency (gamma-band) neural activity in the same area beginning 0.3 s prior to insight solutions. This right anterior temporal area is associated with making connections across distantly related information during comprehension. Although all problem solving relies on a largely shared cortical network, the sudden flash of insight occurs when solvers engage distinct neural and cognitive processes that allow them to see connections that previously eluded them.

Functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) are used to study neural activity in subjects during a verbal task for which they report solutions achieved by insight

Generative processing and false memories: when there is no cost

Encoding manipulations (e.g., levels of processing) that facilitate retention often result in greater numbers of false memories, a pattern referred to as the more is less effect (M. P. Toglia, J. S. Neuschatz, & K. A. Goodwin, 1999). The present experiments explored false memories under generative processing. In Experiments 1-3, using Deese-Roediger-McDermott (DRM) lists with items that were either read or generated, the authors found recognition and recall tests indicated generation effects for true memories but no increases in false memories (i.e., generation at no cost). In Experiment 4, in a departure from the DRM methodology, a cuing procedure resulted in a more is less pattern for congruous generation,and a no cost pattern for incongruous generation. This highlights the critical distinction between these encoding contexts.

Function of hippocampus in "insight" of problem solving

Since the work of Wolfgang Kohler, the process of "insight" in problem solving has been the subject of considerable investigation. Yet, the neural correlates of "insight" remain unknown. Theoretically, "insight" means the reorientation of one's thinking, including breaking of the unwarranted "fixation" and forming of novel, task-related associations among the old nodes of concepts or cognitive skills. Processes closely related to these aspects have been implicated in the hippocampus. In this research, the neural correlates of "insight" were investigated using Japanese riddles, by imaging the answer presentation and comprehension events, just after participants failed to resolve them. The results of event-related functional magnetic resonance imaging (fMRI) analysis demonstrated that the right hippocampus was critically highlighted and that a wide cerebral cortex was also involved in this "insight" event. To the best of our knowledge, this work is the first neuroimaging study to have investigated the neural correlates of "insight" in problem solving.
