The influence of theme identifiability

In the present study, we used the Deese/Roediger-McDermott paradigm to analyze the relationship between theme identifiability of word lists and false memories in adults and children. We conducted two normative studies to determine the identifiability levels for critical unpresented words in 40 associative lists in adults and in 16 associative lists in children. Then, in three experiments, false memories for critical words that were either easy or hard to identify were analyzed in adults and in children 4–5 years old and 11–12 years old. Opposite results were found for adults and children. Lists with highly identifiable critical words produced fewer false memories for adults but more false memories for children. These results suggest that, if they can identify critical words, adults use an identify-to-reject strategy to edit out false memories, whereas, in children, theme identification does not lead to the use of such a monitoring strategy.     

Do French–English Bilingual Children Gesture More Than Monolingual Children?

Previous studies have shown that bilingual adults use more gestures than English monolinguals. Because no study has compared the gestures of bilinguals and monolinguals in both languages, the high gesture rate could be due to transfer from a high gesture language or could result from the use of gesture to aid in linguistic access. In this study we tried to distinguish between those causes by comparing the gesture rate of 10 French–English bilingual preschoolers with both 10 French and 10 English monolinguals. All were between 4 and 6 years of age. The children were asked to watch a cartoon and tell the story back. The results showed the bilingual children gestured more than either group of monolinguals and at the same rate in both French and English. These results suggest that that the bilinguals were not gesturing because they were transferring the high gesture rate from one language to another. We argue that bilinguals might gesture more than monolinguals to help formulate their spoken message.     

Integrating the Unified Theory and Stages of Change to Create Targeted Health Messages

This study investigates the effects of targeted health messages toward reducing fat consumption by applying the unified theory of behavior change ( Fishbein et al., 2001 ) and the stages of change model. In Study 1, affect and outcome expectancies significantly discriminated individuals within each stage of change. In Study 2, affect was more effective in changing intention for precontemplative individuals, whereas outcome expectancies were more effective in changing intention for contemplative individuals. Gender was a higher-order moderator of this relationship: Precontemplative males were more influenced by an affective message, whereas contemplative males were more affected by a cognitive message. For females, a cognitive message was more effective for precontemplative individuals. There were no differences between the messages for contemplative females.     

Overt naming fMRI pre- and post-TMS: Two nonfluent aphasia patients, with and without improved naming post-TMS

Two chronic, nonfluent aphasia patients participated in overt naming fMRI scans, pre- and post-a series of repetitive transcranial magnetic stimulation (rTMS) treatments as part of a TMS study to improve naming. Each patient received 10, 1-Hz rTMS treatments to suppress a part of R pars triangularis. P1 was a ‘good responder’ with improved naming and phrase length; P2 was a ‘poor responder’ without improved naming.Pre-TMS (10 years poststroke), P1 had significant activation in R and L sensorimotor cortex, R IFG, and in both L and R SMA during overt naming fMRI (28% pictures named). At 3 mo. post-TMS (42% named), P1 showed continued activation in R and L sensorimotor cortex, R IFG, and in R and L SMA. At 16 mo. post-TMS (58% named), he also showed significant activation in R and L sensorimotor cortex mouth and R IFG. He now showed a significant increase in activation in the L SMA compared to pre-TMS and at 3 mo. post-TMS (p < .02; p < .05, respectively). At 16 mo. there was also greater activation in L than R SMA (p < .08). At 46 mo. post-TMS (42% named), this new LH pattern of activation continued. He improved on the Boston Naming Test from 11 pictures named pre-TMS, to scores ranging from 14 to 18 pictures, post-TMS (2–43 mo. post-TMS). His longest phrase length (Cookie Theft picture) improved from three words pre-TMS, to 5–6 words post-TMS.Pre-TMS (1.5 years poststroke), P2 had significant activation in R IFG (3% pictures named). At 3 and 6 mo. post-TMS, there was no longer significant activation in R IFG, but significant activation was present in R sensorimotor cortex. On all three fMRI scans, P2 had significant activation in both the L and R SMA. There was no new, lasting perilesional LH activation across sessions for this patient. Over time, there was little or no change in his activation. His naming remained only at 1–2 pictures during all three fMRI scans. His BNT score and longest phrase length remained at one word, post-TMS.Lesion site may play a role in each patient’s fMRI activation pattern and response to TMS treatment. P2, the poor responder, had an atypical frontal lesion in the L motor and premotor cortex that extended high, near brain vertex, with deep white matter lesion near L SMA. P2 also had frontal lesion in the posterior middle frontal gyrus, an area important for naming (Duffau et al., 2003); P1 did not. Additionally, P2 had lesion inferior and posterior to Wernicke’s area, in parts of BA 21 and 37, whereas P1 did not.The fMRI data of our patient who had good response following TMS support the notion that restoration of the LH language network is linked in part, to better recovery of naming and phrase length in nonfluent aphasia.     

Personality vulnerability to stress-related sleep disruption: Pathways to adverse mental and physical health outcomes

This study examined the associations among neuroticism (N), conscientiousness (C), and sleep quality in the context of a life transition. The interactive effects of N and C on the association between sleep quality and mental and physical well-being were also examined. Seventy-seven college freshmen (mean age = 19.5) completed personality measures at the beginning of the academic year, and measures of sleep quality, daily hassles, functional status, depression, and self-assessed health approximately 2 months later. N was negatively and C was positively related to sleep quality, and daily hassles mediated these associations. Poor sleep predicted greater depressive symptoms and poorer functional status for high-N/low-C participants, but not for other N and C profiles. Results suggest that conscientiousness moderates the extent to which high-N individuals are vulnerable to the adverse effects of poor sleep.     

Now or never: How consciousness represents time

Consciousness has a peculiar affinity for presence; conscious states represent their contents as now. To understand how conscious states come to represent time in this way, we need a distinction between a mental state that represents now and one that simply occurs now. A teleofunctional theory accounts for the distinction in terms of the development and function of explicit temporal representation. The capacity to represent a situation explicitly as ‘now’ and compare it with past situations in order to prepare for the future involves the separation of goals from the particular action required to attain them. That is, when a creature is able to consider alternative paths of action, it becomes necessary to conceive of alternate future times as distinct from the present moment. The developmental, functional approach of a teleofunctional theory is promising in its ability to integrate research from diverse empirical fields for support of its claims.     

A Multi‐Source,Multi‐Study Investigation of Job Performance Prediction by Political Skill

Political skill is a social effectiveness construct with a demonstrated capacity to predict job performance. However, because performance prediction research in this area to date has made exclusive use of self‐reports of political skill, and due to frequent distrust of self‐ratings of constructs in important personnel decisions, there is a need to investigate how multiple alternative sources of political skill and job performance measures relate, thus raising both theoretical and methodological issues. In three studies, employing a triadic data collection methodology, and utilising both cross‐sectional and longitudinal designs, this research tested the hypotheses that employee political skill, measured from the perspective of employees' assessor A, will positively predict job performance rated by assessor B (i.e. Hypothesis 1a), and vice versa, that employee political skill measured by assessor B will predict job performance ratings measured by assessor A (i.e. Hypothesis 1b).     

Brand character as a function of brand loyalty

This study investigated the relationship between self-image, brand image, and brand loyalty by asking whether people use products to enhance self-image. Subjects described themselves on an adjective checklist, then listed product brands to which they consider themselves loyal or not loyal. One month later, using the same adjective checklist, subjects described the type of person who would buy a particular brand to which they are loyal and a brand to which they are not loyal for both gender and non-gender related products. Significant differences between the two groups and a high correlation between self and product user ratings, were found.
