Electrophysiological examination of embodiment in vision and action

A wealth of behavioral data has shown that the visual properties of objects automatically potentiate motor actions linked with them, but how deeply are these affordances embedded in visual processing? In the study reported here, we used electrophysiological measures to examine the time course of affordance resulting from the leftward or rightward orientation of the handles of common objects. Participants were asked to categorize those objects using a left- or right-handed motor response. Lateralized readiness potentials showed rapid motor preparation in the hand congruent with the affordance provided by the object only 100 to 200 ms after stimulus presentation and up to 400 ms before the actual response. Examination of event-related potentials also revealed an effect of handle orientation and response-hand congruency on the visual P1 and N1 components. Both of these results suggest that activity in the early sensory pathways is modulated by the action associations of objects and the intentions of the viewer.     

Precipitating events in adolescent suicidal crises: exploring stress-reactive and nonreactive risk profiles

Factors distinguishing adolescents who experienced a precipitating event in the week preceding a suicidal crisis from those who did not were examined. Among 130 suicidal inpatients (mean age = 15.01 years), those who experienced a precipitating event reported significantly lower depressive symptom scores, better perceived problem solving, less suicidal intent, and a lower rate of prior suicide attempts than those without a precipitating event. Levels of trait impulsivity, suicidal ideation, and current attempt status did not differentiate groups. Findings provide preliminary evidence consistent with at least two possible pathways to a suicidal crisis. Clinical implications and future directions are discussed.     

The Impact of Target Base Rate on Training and Transfer of Learning in Airline Luggage Screening: An Examination of Three Base Rate Scenarios

We examined the extent to which transfer of training is impacted by target probability and physical similarity of training and transfer stimuli. Participants performed a luggage screening task where they trained on three base rates of weapon presence as follows: 100%, 50% and 20%; at transfer, participants detected the same weapons (Study 1) or novel weapons (Studies 2 and 3) at a base rate of 20%. In Study 3, we modified training such that all participants observed the same absolute number of weapons (n = 100) across base rate conditions. In Study 1, different base rates did not significantly impact transfer. In Study 2, 100% base rates helped hit rates at transfer but increased false alarms via liberal shifts in decision criteria and slowed detection times. Study 3 revealed no effect of base rates on transfer hit rates; however, training on 100% base rates still led to liberal responding and inflated false alarms.

Team Perceived Trustworthiness in a Complex Military Peacekeeping Simulation

Antecedents to trust (propensity to trust, perceived trustworthiness) and trust behaviors were examined in relation to team performance in a complex eight-mission military peacekeeping simulation. Teams were colocated or distributed and stayed in the same or transferred to a different context at task transfer. In Experiment 1, an ability and competence factor accounted for most of the variance in perceived trustworthiness and greater perceptions of teammates' abilities/competences predicted posttransfer performance. One's perception of how others perceived one's ability/competence increased over missions. In Experiment 2, propensity to trust did not predict performance; however, trust in others' and one's own ability/competence and trust behaviors predicted performance. At task and/or context transfer, teams produced more monitoring and less cooperating language in their communication.     

Co-variation between graphic pattern stability and attentional cost: A clue for the difficulty to produce handwritten traces

Attentional cost incurred for generating handwritten graphic patterns was investigated using a classic dual-task procedure, in which a concurrent reaction time (RT) task was used as an index of the attentional cost incurred by the primary graphic task. Eight right-handed adults had to trace graphic patterns, characterized by a 0°, 45°, 90°, 135° or 180° relative phase and corresponding to shapes ranging from lines to ellipses to circles, while responding by a key press as fast as possible to an auditory signal. The results evidenced a strong and significant correlation between the stability of the produced pattern and the associated attentional cost. The amplitude of the minor and major axes of the produced ellipsoids decreased with the increase of movement frequency, as expected by nonlinear models of oscillatory pattern generation. These findings pave the way to the study for the (coordinative) processes for letter (mal)formation in cursive handwriting.     

Aging and Family Therapy: Exploring The Training and Knowledge of Family Therapists

The present study examined therapists' training in aging issues, and their knowledge and attitudes about aging. One hundred and ninety-one clinicians completed a web-based questionnaire. The majority of respondents reported to have some training in aging issues, although they did not believe it prepared them well to work with older clients. Clinicians reported feeling comfortable working with older adults, yet they also agreed that special training could benefit their work. Knowledge scores were significantly correlated with interest in aging issues, perceived importance of training, perceived competence, and perceived effectiveness in treating older adults. Research and clinical implications are discussed.     

Sustaining Primary Control Striving for Achievement Goals During Challenging Developmental Transitions: The Role of Secondary Control Strategies

Developmental transitions are imbued with ubiquitous uncertainties that undermine goal striving in many otherwise committed individuals. Our seven-month study examined whether cognitive selective secondary control strategies (motivation-focused thinking) facilitate the enactment of achievement goals among young adults experiencing the landmark school to university transition. Sequential regression analyses demonstrated that (a) achievement goals predicted selective secondary control, (b) selective secondary control predicted behavioral selective primary control striving, and (c) selective primary control predicted final course grades. Findings support Heckhausen et al.'s (2010 Heckhausen , J. , Wrosch , C. , &; Schulz , R. ( 2010 ). A motivational theory of life-span development . Psychological Review , 117 , 32 – 60 .[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) proposition that selective secondary control bolsters selective primary control striving and enables goal attainment during difficult transitions.     

Conceptual implicit memory in subclinical depression

Depression adversely affects explicit memory when implicit memory remains intact unless implicit retrieval requires conceptual processes. The impairment of conceptual implicit memory could be the consequence of the completion of implicit memory tests being contaminated by a voluntary retrieval strategy, hence similar results to those in explicit tests are observed. In this study we adopted a method sensitive to the presence of contamination. Depth-of-study-processing effects were observed for the controls completing the explicit version of a word-association task but were absent for the controls completing the implicit version when compound associates were retrieved. This dissociation indicated the adoption of the designated retrieval strategy in each test with the conceptual implicit memory test being uncontaminated. Subclinically depressed participants showed impairment in the explicit version, while for those completing the implicit version there was evidence that they used a voluntary retrieval strategy. The theoretical implications of the findings are discussed.
