Thought-action fusion: a comprehensive analysis using structural equation modeling

Thought-action fusion (TAF), the phenomenon whereby one has difficulty separating cognitions from corresponding behaviors, has implications in a wide variety of disturbances, including eating disorders, obsessive-compulsive disorder, generalized anxiety disorder, and panic disorder. Numerous constructs believed to contribute to the etiology or maintenance of TAF have been identified in the literature, but to date, no study has empirically integrated these findings into a comprehensive model. In this study, we examined simultaneously an array of variables thought to be related to TAF, and subsequently developed a model that elucidates the role of those variables that seem most involved in this phenomenon using a structural equation modeling approach. Results indicated that religiosity, as predicted by ethnic identity, was a significant predictor of TAF. Additionally, the relation between ethnic identity and TAF was partially mediated by an inflated sense of responsibility. Both TAF and obsessive-compulsive symptoms were found to be significant predictors of engagement in neutralization activities. Clinical and theoretical implications are discussed.     

Differential evaluation of residential care programmes for minors

In this study, the results achieved by residential care programs for minors were evaluated. Two measurements were taken, nine months apart, from a total of 175 minors using a monthly observation scale of goals from an Individualised Educational Project. It was found that, in the majority of the dimensions analysed, there were improvements, although they were not the same for all the minors or of the same magnitude. The differential analyses show that variables such as reason for admission and duration of stay modify the results obtained. There was no significant relationship with age or sex. These results are discussed in the light of existing literature.     

Nature and nurture: Williams syndrome across cultures

This study is concerned with ways in which children with Williams syndrome (WS), a rare neurodevelopmental disorder arising from a hemizygous deletion in chromosome band 7q11.23 including the gene for elastin (ELN) and approximately 20 surrounding genes, are affected by social mores of vastly differing cultures: the United States and Japan. WS presents a compelling model for the investigation because its genetic phenotype is well defined and results in an uneven cognitive profile as well as a social phenotype typical of the syndrome including overt over-friendliness toward strangers. While a number of research groups have been studying the cognitive strengths and weaknesses of individuals with WS in various countries, there have not been studies to date that explore the social phenotype in WS across different cultures. This study examines the ways in which social behavior in WS, stemming from specific genetic underpinnings, might be mediated by cultural expectations. We conducted a cross-cultural study using an instrument that measures aspects of sociability commonly found among people with WS. Quantitative analyses revealed a significant effect of diagnostic category in that in both countries, children with WS were rated as significantly higher in global sociability and more likely to approach strangers than were their normal counterparts. There was also an effect of culture, in that regardless of category, WS and normal children in Japan were rated lower than their counterparts in the US. We suggest that the excessively social phenotype of children with Williams syndrome, although markedly present across cultures, appears to vary in its intensity by culture. This is an intriguing illustration of interactions between nature and nurture.     

Time Points: A Gestural Study of the Development of Space–Time Mappings

Human languages typically employ a variety of spatial metaphors for time (e.g., “I'm looking forward to the weekend”). The metaphorical grounding of time in space is also evident in gesture. The gestures that are performed when talking about time bolster the view that people sometimes think about regions of time as if they were locations in space. However, almost nothing is known about the development of metaphorical gestures for time, despite keen interest in the origins of space–time metaphors. In this study, we examined the gestures that English‐speaking 6‐to‐7‐year‐olds, 9‐to‐11‐year‐olds, 13‐to‐15‐year‐olds, and adults produced when talking about time. Participants were asked to explain the difference between pairs of temporal adverbs (e.g., “tomorrow” versus “yesterday”) and to use their hands while doing so. There was a gradual increase across age groups in the propensity to produce spatial metaphorical gestures when talking about time. However, even a substantial majority of 6‐to‐7‐year‐old children produced a spatial gesture on at least one occasion. Overall, participants produced fewer gestures in the sagittal (front‐back) axis than in the lateral (left‐right) axis, and this was particularly true for the youngest children and adolescents. Gestures that were incongruent with the prevailing norms of space–time mappings among English speakers (leftward and backward for past; rightward and forward for future) gradually decreased with increasing age. This was true for both the lateral and sagittal axis. This study highlights the importance of metaphoricity in children's understanding of time. It also suggests that, by 6 to 7 years of age, culturally determined representations of time have a strong influence on children's spatial metaphorical gestures.     

Do you remember what you imagined you would do in that place? The motor encoding cue-failure effect in sighted and blind people

Three experiments examine why the recall of performed actions often fails to profit from provision of retrieval context. A cue failure has, for instance, been demonstrated with cued recall for performed actions in that cued recall is lower than free recall, whereas control conditions show the usual free to cued recall increase for non-enacted material. The first experiment confirms the cue-failure effect and extends the generality of the finding to everyday cue contexts (where the cues are represented by images of the locations associated to the actions), which intuitively should be of general retrieval help. The second experiment shows that the cue-failure effect is also present, even to a greater extent, in congenitally totally blind people; the third experiment suggests how the cue-failure effect may be defeated by means of simultaneous motor and non-motor encoding.

The results are discussed in terms of strategic and non-strategic conceptions of action memory and of the independence of motor and visuospatial codes. This independence appears maintained also in the blind.     

The Comorbidity of Post-traumatic Stress Disorder and Suicidality in Vietnam Veterans

Vietnam veterans (N = 232) recruited from three sources were assessed for suicidal thinking and behaviors, and symptoms of posttraumatic stress disorder (PTSD) and depression. Findings support the notion that suicidal thoughts are prevalent in this group, with veterans in psychotherapy reporting a greater likelihood of such symptoms (82.6%) than veterans in the community (35.7%) or those seeking assistance through a veteran's outreach center (66.7%). Thoughts of ending one's life and a previous suicide attempt were significantly correlated with a diagnosis of PTSD (r = .53, p < .001; and r = .33, p < .001, respectively). Veterans with a diagnosis of PTSD and depression or dysthymia were also more likely to report suicidal thinking and behaviors than veterans with only one of the diagnoses.
