Witnesses’ memory for events and faces under elevated levels of intoxication

Research on alcohol and witness memory has burgeoned over the last decade. However, most studies have tested participants at relatively low breath alcohol concentration (BAC) levels, unrepresentative of those encountered by officers in the field. To examine how higher intoxication levels might impair witness memory for events and faces, the current research tested participants’ ability to recall a mock crime at elevated BAC levels (>.08%). The BAC levels of bar patrons (N?=?138) were recorded before witnessing a video-taped mock crime. Participants were then interviewed using free recall and cued questions and shown a six-person target-present or target-absent lineup. Results show that alcohol negatively affected both the quantity and quality of recall. Regardless of question format, alcohol also reduced the percentage of accurate information elicited from witnesses; however, only cued questions increased the percentage of inaccurate information reported. Intoxication had no effect on identification accuracy. These findings suggest that the encoding and storage systems for faces and events may be impacted differently by alcohol. Our results also highlight the importance of including higher BAC levels when examining the effects of alcohol on witness memory.     

The Style Troika Model: A Structural Model of the Thinking and Creating Styles Scale

Individuals express their creativity through a variety of thinking and creating styles (Wechsler, 2006, 2007). These constructs underlie the Thinking and Creating Styles Scale (TCSS), which is used to identify individuals' creating styles. The aim of this research is to assess the factorial structure of the Portuguese version of the TCSS. Two studies were performed using 414 and 369 Portuguese participants with mean ages of 29.25 and 29.35 years, respectively. Study 1 consisted of an exploratory factor analysis that yielded a three‐factor solution. Study 2 consisted of a confirmatory factor analysis used to test the fit and compare the suitability of several factorial solutions. The three‐factor model (Non‐Conforming/Transformer, Cautious/Reflexive, and Logical/Objective) with the best statistical fit was called the Troika Model. In this model, each factor had five items and showed good and acceptable indices of fit. This new three‐factor structure results in a more efficient and attractive version of the TCSS: the Creating and Thinking Styles‐Troika Scale (CTS‐TS). Future studies should use the CTS‐TS and other creativity assessment instruments to explore the creativity level and style dichotomy.     

Developing an emotion-focused therapy model for fear of cancer recurrence: A case-level task analysis

Fear of cancer recurrence (FCR) involves anxiety about the possible return or progression of the disease. It is common among people surviving cancer, covering a range of adaptive and maladaptive responses including clinical presentations of FCR, for which different psychological interventions have been developed, most within the cognitive-behavioural paradigm. Recently, emotion-focused therapy (EFT) has been proposed as an alternative and has been the subject of research focusing on the cancer population and cancer-related issues, including FCR. In this study, we looked closely at a successful case from a larger exploratory study, carrying out a discovery-phase task analysis aimed at identifying the main components of EFT–FCR. We found that this approach generally followed the usual structure of an EFT intervention, with four distinct phases. However, we identified some specific secondary processes (e.g., hypervigilance and catastrophising) and clarified the nature of the core pain in this presentation as existential (e.g., fear of dying).     

On the dual nature of maternal aggression in rats

Presentation of a natural predator, a cat, was used to differentiate elements of maternal attack by female rats on a male intruder. Following exposure (without direct physical contact) of post-partum females to a cat or to a toy stuffed cat (control group), the females were replaced in their home cages and presented with a male intruder rat. Cat exposure reliably decreased lateral attack to the intruder, as well as locomotion, but had no effect on either jump attack or an upright defensive posture (boxing). Since predator exposure produces a somewhat durable increase in defense, along with inhibition of nondefensive behavior, these results suggest that maternal aggression represents a mixture of offensive, usually related to competition, and defensive (protective) behaviors. The results indicate that maternal aggression, as a parental care behavior, appears to be at least partially resistant to fear. © 1996 Wiley-Liss, Inc.     

Field dependence-independence (FDI) cognitive style: an analysis of attentional functioning

Previous research has indicated that field-dependent children display poorer performance than field-independent children in almost all academic subjects and cognitive tasks. However, the processes underlying this poorer performance remain unclear. The present study aimed to assess whether children with different FDI cognitive styles show differences in performance of tasks measuring aspects of attentional functioning. Specifically, 149 children aged 8 - 11 years were classified according to FDI cognitive style (field-dependent, intermediate, or field-independent), and to storage capacity (Digits Forward Test), verbal working memory (Digits Backward Test), capacity to focus, shift, and maintain attention (Digit Symbol Test), and capacity for sustained attention (Visual Search and Attention Test). Field-independent children displayed better performance than intermediate and field-dependent children on all tests except the Digits Forward Test. Theoretical and practical implications of these results are discussed.     

Remembering more than meets the eye: a study of memory confusions about incomplete visual information

The purpose of this series of four experiments was to examine the possible role of spontaneous imagery in memory confusions about the way in which visual information had been experienced. After viewing pictures of familiar objects, complete or incomplete in visual form, participants were asked to remember the way in which the objects had been presented. Although, as predicted, memory for the objects themselves was quite good, participants falsely remembered seeing complete versions of pictures that were actually presented as incomplete. These false reports were observed across a variety of encoding and testing conditions. The results suggest that the false reports (referred to here as completion errors) are due to internal representations based on filling-in processes in response to the encoding of incomplete visual information. As such, the results also speak to alternative explanations for the completion errors and, more broadly, to theoretical perspectives that draw on filling-in processes when accounting for object identification and object memory.     

Field-dependence-independence and career counseling: directions for research

This paper reviews relevant research concerning the utilization of Field-dependence-independence cognitive style in vocational decision-making as well as in implementation and adjustment of career choices. Need for further investigation is highlighted and how career interventions can be enriched by including cognitive style indicated. A test of cognitive styles offers complementary information to traditional career counseling but needs to be explicitly integrated into personal history, academic experiences, achievements, motivations, and vocational goals. New directions for research are offered.     

The locus of the frequency effect in picture naming: When recognizing is not enough

The lexical frequency effect in picture naming is generally assumed to constitute a signature of lexical access. Lexical frequency, however, is correlated with other variables, like concept familiarity, that can produce effects similar to those of lexical frequency in picture naming tasks. In this study, a delayed picture naming task was employed to address the hypothesis that the frequency effect in picture naming is due to variables that affect processing in the perceptual and semantic identification stages (i.e., input stages). Despite the fact that all the input processing stages were completed prior to the presentation of the naming cue, a strong frequency effect was still obtained in this task. These results establish that the lexical frequency effect is independent of variables affecting the input stages of picture naming, and, hence, confirm the lexical frequency effect as a signature effect of lexical access.     

Transthyretin influences spatial reference memory

Transthyretin (TTR) is a plasma and cerebrospinal fluid carrier for thyroxine and retinol, described also to sequester the amyloid beta peptide. TTR levels have been described as decreased in the cerebrospinal fluid of patients with Alzheimer's disease. In order to investigate the role of TTR in learning and memory, we studied young adult and old TTR-null 129/Sv mice for cognitive performance. In the absence of TTR, 5-month-old mice display spatial reference memory impairment when compared to age-matched wild-type mice. Interestingly, while aging in wild-type mice is associated with a worsening reference memory performance, TTR-null mice show no further impairment with increasing age. As a result, no significant differences were found in this spatial reference task in old mice. Our data show that the absence of TTR seems to accelerate the poorer cognitive performance normally associated with aging.
