Remarkably reproducible psychological (memory) phenomena in the classroom: some evidence for generality from small-N research

BACKGROUND

Mainstream psychology is experiencing a crisis of confidence. Many of the methodological solutions offered in response have focused largely on statistical alternatives to null hypothesis statistical testing, ignoring nonstatistical remedies that are readily available within psychology; namely, use of small-N designs. In fact, many classic memory studies that have passed the test of replicability used them. That methodological legacy warranted a retrospective look at nonexperimental data to explore the generality of the reported effects.

METHOD

Various classroom demonstrations were conducted over multiple semesters in introductory psychology courses with typical, mostly freshman students from a predominantly white private Catholic university in the US Midwest based on classic memory experiments on immediate memory span, chunking, and depth of processing.

RESULTS

Students tended to remember 7 ± 2 digits, remembered more digits of π following an attached meaningful story, and remembered more words after elaborative rehearsal than after maintenance rehearsal. These results amount to replications under uncontrolled classroom environments of the classic experiments originally conducted largely outside of null hypothesis statistical testing frameworks.

CONCLUSIONS

In light of the ongoing replication crisis in psychology, the results are remarkable and noteworthy, validating these historically important psychological findings. They are testament to the reliability of reproducible effects as the hallmark of empirical findings in science and suggest an alternative approach to commonly proffered solutions to the replication crisis.

How to True Psychology’s Objects

Psychology’s current crisis attends most visibly to perceived problems with statistical models, methods, publication practices, and career incentives. Rarely is close attention given to the objects of inquiry—to ontological matters—yet the crisis-related literature does features statements about the nature of psychology’s objects. Close analysis of the ontological claims reveals discrepant understandings: some researchers assume objects to be stable and singular while others posit them to be dynamic and complex. Nevertheless, both views presume the objects under scrutiny to be real. The analysis also finds each of these ontological claims to be associated not only with particular method prescriptions but also with distinct notions of the scientific self. Though both take the scientific self to be objective, one figures the scientist as not always a rational actor and, therefore, requiring some behavior regulation, while the other sees the scientist as largely capable of self-governing sustained through painstakingly acquired expertise and self-control. The fate of these prevalent assemblages of object, method, and scientific self remains to be determined, yet as conditions of possibility they portend quite different futures. Following description of the assemblages, the article ventures a futuristic portrayal of the scientific practices they each might engender.

The objectivity and subjectivity of pain practices in older adults with dementia: A critical reflection

Providing nursing care for people with dementia residing in long-term care facilities poses specific challenges regarding pain practices. With underlying communication barriers unique to dementia pathologies, this population is often unable to communicate verbal sentiments and descriptions of pain. In turn, nurses caring for older persons with dementia have difficulty assessing, managing and treating pain. Objectivity is an imperative factor in healthcare pain practices; however, it is difficult to objectively evaluate someone who cannot accurately communicate their experience of pain. Therefore, the authors believe that subjectivity is also an essential part of evaluating the person with dementia's experience of pain. In this critical reflection, the authors explore objectivity and subjectivity in relation to pain practices for dementia in long-term care. A historical summary of pain is provided outlining the evolution of objectivity and subjectivity related to pain practices. The authors discuss the complexities of assessing and managing pain and offer a new perspective about the role of objectivity (and co-existence of subjectivity) for nurses treating pain in the older adults with dementia.

Historically recontextualizing Sidman's Tactics: How behavior analysis avoided psychology's methodological Ouroboros

Psychology is undergoing major cultural changes methodologically, with efforts to redefine how psychologists analyze and report their data. Davidson (2018) argued that psychology's methodological crises stem from mechanical objectivity involving the adoption of an analytic tool as source of dependable knowledge. This has led to institutionalization, and eventually uncritical ritualistic use, such as happened with null hypothesis statistical testing. Davidson invoked the mythological symbol of the Ouroboros to represent the endless churning of statistical fads. Sidman (1960), in his Tactics of Scientific Research provided a shield from these problems in terms of the premium he placed on the experience, expertise, judgement, and decision-making of the scientist, that appear to be absent in psychology's ritualized processes.
