Is the Brain a Quantum Computer?

We argue that computation via quantum mechanical processes is irrelevant to explaining how brains produce thought, contrary to the ongoing speculations of many theorists. First, quantum effects do not have the temporal properties required for neural information processing. Second, there are substantial physical obstacles to any organic instantiation of quantum computation. Third, there is no psychological evidence that such mental phenomena as consciousness and mathematical thinking require explanation via quantum theory. We conclude that understanding brain function is unlikely to require quantum computation or similar mechanisms.     

Retrospective bias in test performance: Providing easy items at the beginning of a test makes students believe they did better on it

We examined the effect of three variables (test list structure, report option, and framing) on retrospective bias in global evaluations of test performance (postdictions). Participants answered general knowledge questions and estimated correctness of their performance after each block. The ordering of the questions within a block affected bias: Participants believed they had answered more questions correctly when questions were sorted from the easiest to the hardest than when the same questions were randomized or sorted from the hardest to the easiest. This bias was obtained on global postdictions but was not apparent on item-by-item ratings, pointing to a memory-based phenomenon. In addition, forcing participants to produce a response to every question increased performance without affecting evaluations. Finally, framing the evaluation question in terms of the number of questions answered incorrectly (rather than the number correctly answered) did not affect how positively participants evaluated their performance, but did render postdictions less accurate. Our results provide evidence that students’ evaluations of performance after a test are prone to retrospective memory biases.     

Adapting to test structure: Letting testing teach what to learn

We propose that we encode and store information as a function of the particular ways we have used similar information in the past. More specifically, we contend that the experience of retrieval can serve as a powerful cue to the most effective ways to encode similar information in comparable future learning episodes. To explore these ideas, we did two studies in which all participants went through study–test cycles of single category lists while we manipulated the nature of the recognition tests. The recognition tests either included only same-category lures or only different-category lures. The experience of repeated testing leads participants to avoid conceptual-based strategies but only when conceptual knowledge was poorly diagnostic for recognition (i.e., in the same-category lures condition). In a second study with a similar manipulation, we showed that repeated testing with lures from the same category as study items improved performance in a final recall surprise test compared to conditions in which different-category lures were used. Such a difference is akin to the one obtained when encoding instructions focus on distinctive item features compared to cases in which the focus is on relational processing. We suggest that testing requirements lead to adaptive changes at encoding.     

A Szondi Study of Developmental and Cultural Factors in Personality: The Seven-Year-Old

Children's concepts of various social roles were examined in a task that required the child to indicate the similarity of two occupants of common social roles. Each occupant in the pair was described differently in terms of behaviors appropriate for a particular role. Children in the first, third, and sixth grades were studied. Findings indicated that children in the youngest group held role concepts based primarily on concrete actions, while role concepts of the older two groups were based on more abstract, general role functions. In addition, there is some suggestion that the level of role conceptualization is related to the relevance of the particular role.     

Three Views of Artful Practice in Psychosocial Occupational Therapy

This qualitative study explored artfulness in the psychosocial practice of three occupational therapists through in-depth observation and interviews. Analysis focused on the therapist-client relationship, activity use, self-reflection, and the change process. Each therapist established an interpersonal connection while offering meaningful, engaging activities. In addition, each brought a distinct and unique personal view to treatment. Findings suggest that the art of practice in occupational therapy is constructed by the therapist's integrated balance of substance, form, and vision to achieve a coherent whole, which positively influences the personal views of substance, form, and vision in clients.     

Beauty is in the eye of the psychologically fulfilled: How need satisfying experiences shape aesthetic perceptions of spaces

Individuals perceive beauty as a function of physical attributes paired with the subjective experience of an object or a space. Yet, little or no research has investigated how either relational or emotional experiences shape perceptions of the physical world. Four studies were conducted to address this question using self-determination theory (Ryan and Deci in Psychol Inq 11:319–338, 2000) as a guiding framework. Studies 1 and 2 indicated that satisfaction of the needs for competence, relatedness, and autonomy in one’s childhood home was linked to perceptions of beauty directly and indirectly through emotions of the past (recollections of happiness) and present (nostalgia). Two additional studies focused on present-day spaces. In Study 3, we found that need satisfaction impacted perceptions of the university campus as beautiful. In a final study, we manipulated needs in the lab to identify a causal model of aesthetic perceptions. Findings are contextualized within the self-determination theory and perceived beauty literatures.     

Infertility and Adjustment in Women: The Effects of Attachment Style and Social Support

The moderating effects of two psychological resources—attachment style and perceived social support—on adjustment were studied in 109 infertile women, examining the effects of duration of infertility and of primary (the woman has no child of her own) versus secondary (the woman already has a child of her own) infertility. Subjects were administered questionnaires measuring marital adjustment, psychological distress, and well-being. A model viewing attachment style and social support as moderators between stress psychological well-being was explored. The results showed that among the objective characteristics, only duration of infertility had any impact on the psychological measures. Furthermore, the psychological resources were highly associated with the adjustment scores in general. A hierarchical regression analysis showed that attachment style and social support both were related to marital quality and to psychological well-being and that these two resources function as stress moderators. It was concluded that attachment style and social support are important resources for individuals in times of stress, as exemplified in the infertility situation.
