Reliability and factor structure of the Finnish version of the Sport Imagery Questionnaire

The aim of this study was to examine the reliability and factor structure of the Finnish version of the Sport Imagery Questionnaire, a measure which examines cognitive and motivational functions of imagery. The final sample comprised 231 participants drawn from 34 sports and ranging in age from 14 to 49 years (M = 20.9, SD = 5.8). Internal consistency and confirmatory factor analyses were undertaken to evaluate the reliability and factorial validity of the scale. Fit indices and modification data generated from examining the 30-item five-factor model were equivocal, suggesting minor amendment and recategorization of several items rather than major adjustment to the proposed latent factor structure. Cronbach coefficients alpha indicated the scale is reliable. Overall, these results provide positive additional support for the claim that the Sport Imagery Questionnaire has a reproducible factor structure and is a reliable test for measuring imagery use in Finnish athletes.     

What is learned when concept learning fails?—A theory of restricted-domain relational learning

Two matching-to-sample (MTS) and four same/different (S/D) experiments employed tests to distinguish between item-specific learning and relational learning. One MTS experiment showed item-specific learning when concept learning failed (i.e., no novel-stimulus transfer). Another MTS experiment showed item-specific learning when pigeons’ novel-stimulus transfer decreased because they chose familiar training comparisons instead of matching novel comparisons. In 8-item and 3-item S/D tasks, pigeons and monkeys were accurate with unfamiliar training-stimulus pairings, stimulus inversions, and distorted stimuli, suggesting relational learning within a domain restricted to the training stimuli (i.e., no novel-stimulus transfer). In 32-item S/D tasks, pigeons with previous 8-item training showed less transfer than those without prior training, suggesting a carryover of restricted-domain relational learning. Pigeons shifted from 1024-item to 8-item S/D tasks showed reinstatement of restricted-domain relational learning. These findings are important in specifying which types of learning occur in these tasks, showing that subjects failing novel-stimulus transfer are not required to switch from item-specific to relational learning as a training set is expanded, and demonstrating that concept learning failure is not proof of item-specific learning.     

Undergraduate psychology students' experiences of volunteering at a chronic mental health facility

A volunteer program for undergraduate psychology students at a chronic mental health facility was evaluated. All 53 volunteers found the program beneficial, 96.2% reported improved understanding of psychopathology, 98.1% noted increased knowledge of the mental health care system, 86.8% reported increased interest in clinical psychology, and 47.2% felt less anxious about working with persons with mental illness as a result of the program.     

The effect of midazolam on implicit and explicit memory in category exemplar production and category cued recall

Transfer‐appropriate processing theory (Roediger, Weldon, & Challis, 1989) proposes that dissociations between performance on explicit and implicit memory tests arise because these tests often rely on different types of information processing (e.g., perceptual processing vs conceptual processing). This perspective predicts that implicit and explicit memory tasks that rely primarily on conceptual processing should show comparable results, not dissociations. Numerous studies have demonstrated such similarities. It is, however, possible that these results arise from explicit memory contamination of performance on implicit memory tasks. To address this issue, an experiment was conducted in which participants were administered the sedative midazolam prior to study. Midazolam is known to create a temporary, but dense, period of anterograde amnesia. The effects of blocking stimulus materials by semantic category at study and generation at study were investigated on category exemplar production and category‐cued recall. The results of this study demonstrated a dissociation of the effects of midazolam on category exemplar production and category‐cued recall. Specifically, midazolam reduced the effect of blocking stimulus materials in category‐cued recall, but not in category exemplar production. The differential effect of midazolam on explicit and implicit memory is at odds with transfer‐appropriate processing theory and suggests that theories of memory must distinguish the roles of different types of conceptual processing on implicit and explicit memory tests.     

Lexicality and phonological similarity: A challenge for the retrieval‐based account of serial recall?

The retrieval‐based account of serial recall () attributes lexicality, phonological similarity, and articulatory suppression effects to a process where long‐term representations are used to reconstruct degraded phonological traces. Two experiments tested this assumption by manipulating these factors in the recall of four‐ and five‐item lists of words and non‐words. Lexicality enhanced item recall (IR), but only affected position accuracy (PA) for five‐item lists under suppression. Phonological similarity influenced both words and non‐words, and produced impaired PA in silent and suppressed conditions. Consistent with the retrieval‐based account, words and non‐words of high word‐likeness appear subject to redintegration. However, some findings, like suppression not reducing the phonological similarity impairment in suppressed conditions, present challenges for the retrieval‐based account and other models of serial recall.     

Correlates of Dispositional and State Flow in Tennis Competition

The purpose of this study was to investigate the relationship between psychological correlates and flow in tennis competition. Using a cross-sectional design, the sample of 261 junior tennis athletes showed moderate-to-strong correlations between flow (dispositional and state) and confidence (r _disp = .59; r _state = .35), imagery use (r _disp = .58; r _state = .32), and action control (r _disp = .41; r _state = .40), whereas absorption was orthogonal to flow. Commonality analysis revealed that imagery and confidence accounted for 34.2% of the variance in dispositional flow. The results are discussed for the development of intervention studies in order to enhance flow in competition.     

Mad Scientists, Narrative, and Social Power: A Collaborative Learning Activity

Nathaniel Hawthorne’s short stories “The Birthmark” (1843) and “Rappaccini’s Daughter” (1844) encourage critical thinking about science and scientific research as forms of social power. In this collaborative activity, students work in small groups to discuss the ways in which these stories address questions of human experimentation, gender, manipulation of bodies, and the role of narrative in mediating perceptions about bodies. Students collectively adduce textual evidence from the stories to construct claims and present a mini-argument to the class, thereby strengthening their skills in communication and cooperative interpretation of ethical dilemmas. This exercise is adaptable to shorter and longer periods of instruction, and it is ideal for instructors who collaborate across areas of expertise.
