Virtual Reality Exposure Therapy for PTSD symptoms after a road accident: an uncontrolled case series

This report examined whether Virtual Reality Exposure Therapy (VRET) could be used in the treatment of posttraumatic stress disorder (PTSD) symptoms in the aftermath of a serious motor vehicle accident. Six individuals reporting either full or severe subsyndromal PTSD completed 10 sessions of VRET, which was conducted using software designed to create real-time driving scenarios. Results indicated significant reductions in posttrauma symptoms involving reexperiencing, avoidance, and emotional numbing, with effect sizes ranging from d=.79 to d=1.49. Indices of clinically significant and reliable change suggested that the magnitude of these changes was meaningful. Additionally, high levels of perceived reality ("presence") within the virtual driving situation were reported, and patients reported satisfaction with treatment. Results are discussed in light of the possibility for VRET to be useful in guiding exposure in the treatment of PTSD following road accidents.     

Can emotions be truly group level? Evidence regarding four conceptual criteria

Recent advances in understanding prejudice and intergroup behavior have made clear that emotions help explain people's reactions to social groups and their members. Intergroup emotions theory (D. M. Mackie, T. Devos, & E. R. Smith, 2000; E. R. Smith, 1993) holds that intergroup emotions are experienced by individuals when they identify with a social group, making the group part of the psychological self. What differentiates such group-level emotions from emotions that occur purely at the individual level? The authors argue that 4 key criteria define group-level emotions: Group emotions are distinct from the same person's individual-level emotions, depend on the person's degree of group identification, are socially shared within a group, and contribute to regulating intragroup and intergroup attitudes and behavior. Evidence from 2 studies supports all 4 of these predictions and thus points to the meaningfulness, coherence, and functionality of group-level emotions.     

Nonstandard career paths and profiles of commitment to life roles: A complex relation

The career paths (ascending, interesting, uninteresting, descending) of 124 White Canadian francophones (62 men, 62 women) who had experienced nonstandard and precarious work for the last three years were examined in relation to the participants’ profiles of commitment to three life roles (work, family, and duality, that is, investment in both career and family). The paths were derived from the content analysis of the data collected through semi-structured individual interviews. Quantitative tools were used to assess the importance of life roles and to compare the career paths as well as the commitment profiles with respect to specific and general anxiety. Among other results, a significant relationship was found between unsatisfying career paths and the duality profile, on the one hand, and higher levels of specific and general anxiety, on the other. The results are discussed with respect to the scientific literature. Implications for career counseling are suggested.     

Visualization,pattern recognition,and forward search: effects of playing speed and sight of the position on grandmaster chess errors

A new approach examined two aspects of chess skill, long a popular topic in cognitive science. A powerful computer‐chess program calculated the number and magnitude of blunders made by the same 23 grandmasters in hundreds of serious games of slow (“classical”) chess, regular “rapid” chess, and rapid “blindfold” chess, in which opponents transmit moves without ever seeing the actual position. Rapid chess led to substantially more and larger blunders than classical chess. Perhaps more surprisingly, the frequency and magnitude of blunders did not differ in rapid versus blindfold play, despite the additional memory and visualization load imposed by the latter. We discuss the involvement of various cognitive processes in human problem‐solving and expertise, especially with respect to chess. Prior opposing views about the basis of general chess skill have emphasized the dominance of either (a) swift pattern recognition or (b) analyzing ahead, but both seem important and the controversy appears currently unresolvable and perhaps fruitless.     

Cross-language facilitation,semantic blindness,and the relation between language and memory: A reply to Altarriba and Soltano

This comment corrects some inaccuracies, points to some methodological problems, and makes three substantive observations regarding the Altarriba and Soltano (1996) article. First, token individuation theory does not explain what is new and interesting in the Altarriba and Soltano data, namely cross-language semantic facilitation in lists and a list-sentence effect, that is, a large difference in the effect of semantic repetition when identical translation equivalents occurred in sentences versus lists. Second, Altarriba and Soltano’s small and nonsignificant semantic blindness effect for translation equivalents in split-language sentences is attributable to the peculiar nature of their materials, procedures, analyses, and experimental design. These problems nullify their conclusion that semantic blindness does not occur, and we discuss several clear cases where semantic blindness has been demonstrated. Finally, we suggest an explanation for Altarriba and Soltano’s unexplained effects (cross-language facilitation and the list-sentence effect) and show why these effects are important for the general issue of relations between language and memory.     

REPETITION BLINDNESS INTERACTS WITH SYNTACTIC GROUPING IN RAPIDLY PRESENTED SENTENCES

Abstract— This study rested for predicted effects of syntax on a repetition deficit (RD) known as repetition blindness, the reduced probability of recall for repeated words in rapid serial visual presentation (RSVP) sentences The syntactic variable was phrase-congruent versus phrase-incongruent grouping within simultaneous RSVP displays With phrase-congruent grouping, each RSVP display contained a syntactic phrase (e g, "to play sports" in the sentence "They wanted to play sports but sports were not allowed"), whereas with phrase-incongruent grouping, RSVP displays contained nonphrases (e g, "sports but sports") RD was extensive with phrase-incongruent grouping (29%), but nonsignificant (6%) with phrase-congruent grouping, as if phrase-congruent groups free up the extra processing time needed to connect repeated words into phrases in rapidly presented sentences, enabling top-down retrieval of the phrases during recall The present results comport with effects of syntax and prosody on auditory RD, and suggest that visual and auditory RD are identical underlying phenomena.     

A note on the analysis of designs in which subjects receive each stimulus only once

In social psychological experiments, the manipulations of interest are often presented to subjects along with, or as part of, some stimulus. An example would be a manipulation of the verbal label associated with a stimulus photograph, in a person perception study. Ordinarily it is not possible for stimuli to be completely crossed with treatments because subjects cannot be exposed to any stimulus more than once. In such designs it is wise to counterbalance the assignment of stimuli to treatment conditions, but this gives rise to difficulties in the analysis of the experimental data. Data from such designs have frequently been misanalyzed in the published literature. This paper presents a method of constructing a counter-balancing scheme to simplify the analysis, and appropriate methods of analysis for both the simplified and the general case. It is emphasized that stimuli are generally best treated as a random factor in such designs, permitting increased generalizability, but the case where the stimulus factor is fixed is also considered.     

Dewey Between the Lines: George Kelly and the Pragmatist Tradition

In his own somewhat sly and sardonic way, George Kelly always insisted that personal construct theory could not be assimilated into any other kind of psychology. We believe this was not an example of Kelly being difficult or protecting his turf, but that he resisted such efforts at categorization because he formulated personal construct psychology from an entirely different set of assumptions than those which have traditionally guided the construction of psychological theories. We begin by looking at the unusual life path Kelly took in order to enter the field of psychology and what it reveals about the independent turn of mind he brought to creating his own theory of personality. We then examine what we believe is the single most important influence on Kelly's thinking—the tradition of American pragmatism, in general, and the philosophy and psychology of John Dewey, in particular. We argue that Kelly embraced the pragmatic epistemological assumptions that guided Dewey's work, and that he used these assumptions to develop the only pragmatic theory of personality and psychotherapy. It is, in fact, the influence of Dewey and the pragmatists that makes personal construct psychology so different from and, at times, more difficult to understand than other, more traditional, “realist” theories, but it is also this pragmatic orientation that makes Kelly's theory such an important contribution.
