Pre-Motor and Motor Reaction Time Differences Associated with Stretching of the Hamstring Muscles

Pre-motor and motor RT scores were obtained from 24 male Ss using a knee flexion task. It was predicted that an increased arousal state due to proprioceptive feedback from stretched hamstring muscles would shorten pre-motor RT while motor RT would shorten because of changes in muscle tension development due to changes in the series elastic and/or contractile components of the muscle tissue. A finger RT task was also included in order to determine whether other factors not related to changes in the stretch of the hamstring muscles were operative. Motor RT decreased with increased muscle stretch and constituted 46% of leg RT. Pre-motor RT as well as finger RT increased rather than decreased with increased muscle stretch. No relationship was found between pre-motor and motor RT indicating that lags in CNS processing are independent of lags associated with the rate of muscular tension development.     

A Girl's Loyalty to her Mother

This paper explores the alliance between the analytic couple and the analytic process. The patient doesn't ally only with the analyst, but also with the unfolding of an experiential world. The developmental origins of this alliance are described in terms of infant and child being inside a forming intelligence; womb, mother and family—transforming the mental state of the subject. The structure of the experience is pictured by the resemblance to a simple—experiencing—self being inside a dream, and a rhetoric “I” speaking in an internal dialogue to an unanswering, but present, “you”. The writer describes the negative therapeutic reaction as an attempt to break into this forming intelligence; as an attempt to see who is the creator of the experiential universe. Staying inside the unfolding process is further investigated through the experiences of aloneness and presential immediateness.     

L1 effects on the processing of inflected nouns in L2

This study investigated the effect of L1 on the recognition of L2 Swedish inflected nouns. Two groups of late L2 learners with typologically very different native languages, Hungarian (agglutinative) and Chinese (isolating), participated in a visual lexical decision experiment. The target words were matched inflected vs. monomorphemic nouns from three frequency levels. The Hungarian group showed a morphological processing cost (longer reaction times for the inflected words) for low and medium frequency words but not for high frequency words, suggesting morphological decomposition of low and medium frequency Swedish inflected nouns. In contrast, for the Chinese group the reaction times of the inflected vs. monomorphemic words were similar at all frequency levels, indicating full-form processing of all the inflected nouns. This cross-language difference suggests that L1 can exert an effect on the morphological processing in L2. The application of full-form processing for the Swedish inflected nouns in the Chinese group might reflect strategy transfer from their isolating native language to Swedish.     

The Importance of Assessing for Childhood Abuse and Lifetime PTSD in Bariatric Surgery Candidates

For bariatric surgery candidates, history of child abuse and PTSD may be under-recognized or under-reported at pre-surgical evaluation. On a range of clinically relevant factors, we studied 3045 candidates for bariatric surgery: (1) those with a history of childhood abuse compared to those without such history; and (2) among candidates with a history of abuse, those with a lifetime diagnosis of PTSD compared to those without that diagnosis. We compared them on current and lifetime eating disorders, physical health problems, health behaviors, physical functioning, psychosocial functioning, psychiatric disorders, emotional wellness, body satisfaction, and self-esteem. We hypothesized that patients with a history of childhood abuse, and within that group, those with a lifetime PTSD diagnosis, would display greater overall impairment. Patients were interviewed with semi-structured interviews and completed self-report questionnaires. Results showed that (1) patients with a history of childhood abuse exhibited significantly greater impairment than those without abuse; and (2) among candidates with a history of abuse, those with a lifetime history of PTSD displayed significantly greater impairment than those without a PTSD diagnosis. The findings suggest that a history of both childhood abuse and lifetime PTSD should be thoroughly assessed for at pre-surgical evaluation, and that greater attention be paid to the experience of PTSD symptoms in abuse survivors presenting for bariatric surgery.     

Peers increase adolescent risk taking by enhancing activity in the brain's reward circuitry

The presence of peers increases risk taking among adolescents but not adults. We posited that the presence of peers may promote adolescent risk taking by sensitizing brain regions associated with the anticipation of potential rewards. Using fMRI, we measured brain activity in adolescents, young adults, and adults as they made decisions in a simulated driving task. Participants completed one task block while alone, and one block while their performance was observed by peers in an adjacent room. During peer observation blocks, adolescents selectively demonstrated greater activation in reward-related brain regions, including the ventral striatum and orbitofrontal cortex, and activity in these regions predicted subsequent risk taking. Brain areas associated with cognitive control were less strongly recruited by adolescents than adults, but activity in the cognitive control system did not vary with social context. Results suggest that the presence of peers increases adolescent risk taking by heightening sensitivity to the potential reward value of risky decisions.     

Attributional Retraining: reducing the likelihood of failure

Failing a course is an acutely negative event for first-year university students, and a major contributor to high attrition rates at North American universities. Despite its prevalence, course failure receives relatively little research attention. What can be done to reduce course failure and help first-year students remain in university? This study examined the efficacy of an Attributional Retraining treatment intervention to reduce course failure in an Introductory Psychology course. Attributional Retraining is designed to restructure students’ causal explanations of poor performance by encouraging controllable attributions such as effort and strategy in place of immutable causes such as academic ability or intelligence. Relative to students in the control group, first-year students who received Attributional Retraining were less likely to fail the Introductory Psychology course (14.6% vs. 6.4%). This finding emerged beyond the effects of several well-established predictors of academic outcomes including student background characteristics (i.e., age, gender, and past academic performance) and learning environment variables (student registration status and participation in a first-year orientation program), suggesting the utility of Attributional Retraining for students with varying backgrounds and in different educational contexts. To the extent that Attributional Retraining is effective, inexpensive, and relatively easy to administer it may be a viable option for inclusion in orientation programs designed to reduce course failure and attrition among first-year university students.     

Deficits in perceived social support associated with generalized social phobia

Social phobia is a common anxiety disorder associated with significant impairment in social and occupational functioning. To date, few studies have examined the relationship between social phobia and perceived social support, a construct with important relationships to physical and mental health. The present study examined data from 2 widely used measures of perceived social support administered to 132 individuals with DSM-IV generalized social phobia. These data were compared with those obtained from a healthy control group and from several clinical and non-clinical samples reported in the literature. Persons with generalized social phobia scored significantly lower on both measures of social support compared with all other groups. It is suggested that deficits in perceived social support associated with generalized social phobia may play a role in the development of co-morbid problems and should be explicitly targeted by treatments for social phobia. Low correlations between perceived social support and social anxiety measures suggest that perceived support should be specifically evaluated in this population.     

How do people learn to allocate resources? Comparing two learning theories

How do people learn to allocate resources? To answer this question, 2 major learning models are compared, each incorporating different learning principles. One is a global search model, which assumes that allocations are made probabilistically on the basis of expectations formed through the entire history of past decisions. The 2nd is a local adaptation model, which assumes that allocations are made by comparing the present decision with the most successful decision up to that point, ignoring all other past decisions. In 2 studies, participants repeatedly allocated a capital resource to 3 financial assets. Substantial learning effects occurred, although the optimal allocation was often not found. From the calibrated models of Study 1, a priori predictions were derived and tested in Study 2. This generalization test shows that the local adaptation model provides a better account of learning in resource allocations than the global search model.     

Unpackaging Manager Mistrust in Allowing Telework: Comparing and Integrating Theoretical Perspectives

Purpose

We developed and tested an integrative model centering on the significance of trust as a basis for managers’ decisions about allowing versus prohibiting their employees to telework. We examined the importance of trust in relation to several other factors managers may consider in making telework decisions including coordination and communication, equity, and a desire to accommodate employees.

Design/Methodology/Approach

Study 1 was a policy capturing investigation of 71 respondents intended to document the relative importance and interactions among trust and these other theoretically based factors. Study 2 was a test of the full theoretical model based on the responses of 85 managers who reported on these considerations for the 191 employees about whom they make telework decisions.

Findings

Results from the two studies were largely consistent. Managers’ assessments of employees’ conscientiousness and trustworthiness were paramount in predicting telework allowance, with the other theoretically based considerations generally failing to attenuate the importance of those personal assessments.

Implications

Organizations wishing to increase the use of telework (e.g., by implementing manager telework training) must directly address managers’ mistrust as a factor underlying this resistance. Job-related and technological changes may not dampen the effects of mistrust.

Originality

To our knowledge, this is the most comprehensive and theoretically grounded assessment of the various considerations factoring into managers’ telework decisions.
