Reach out to one and you reach out to many: Social touch affects third‐party observers

Casual social touch influences emotional perceptions, attitudes, and behaviours of interaction partners. We asked whether these influences extend to third‐party observers. To this end, we developed the Social Touch Picture Set comprising line drawings of dyadic interactions, half of which entailed publicly acceptable casual touch and half of which served as no‐touch controls. In Experiment 1, participants provided basic image norms by rating how frequently they observed a displayed touch gesture in everyday life and how comfortable they were observing it. Results implied that some touch gestures were observed more frequently and with greater comfort than others (e.g., handshake vs. hug). All gestures, however, obtained rating scores suitable for inclusion in Experiments 2 and 3. In Experiment 2, participants rated perceived valence, arousal, and likeability of randomly presented touch and no‐touch images without being explicitly informed about touch. Image characters seemed more positive, aroused, and likeable when they touched as compared to when they did not touch. Image characters seemed more negative and aroused, but were equally likeable, when they received touch as compared to when there was no physical contact. In Experiment 3, participants passively viewed touch and no‐touch images while their eye movements were recorded. Differential gazing at touch as compared to no‐touch images emerged within the first 500 ms following image exposure and was largely restricted to the characters' upper body. Gazing at the touching body parts (e.g., hands) was minimal and largely unaffected by touch, suggesting that touch processing occurred outside the focus of visual attention. Together, these findings establish touch as an important visual cue and provide novel insights into how this cue modulates socio‐emotional processing in third‐party observers.     

Rapid serial visual presentation display on a small screen: reading Chinese while walking

This study examined the effects of presentation unit (word-by-word or single line) and presentation duration [171, 213, 240, and 308 msec. per character (msec./C)] on the comprehension of Chinese rapid serial visual presentation (RSVP) displays read from the small screen of a mobile phone in three different contexts (seated, walking on a treadmill, and walking through an outdoor course). 30 native Chinese readers ages 19 to 26 were recruited as participants. Scores on reading comprehension showed that presentation unit and presentation duration significantly affected reading comprehension, and interactions between factors were also significant. When the presentation unit was word-by-word, no significant difference in reading comprehension was observed under different presentation durations. However, when the presentation unit was a single line, reading comprehension deteriorated with the shortest presentation duration of 171 msec./C. With regard to context, participants had a higher mean reading comprehension score in the seated context than in walking contexts, but the difference was not significant.     

Increased levels of conditioned fear and avoidance behavior coincide with changes in phosphorylation of the protein kinase B (AKT) within the amygdala in a mouse model of extremes in trait anxiety

Patients diagnosed for anxiety disorders often display faster acquisition and slower extinction of learned fear. To gain further insights into the mechanisms underlying these phenomenona, we studied conditioned fear in mice originating form a bi-directional selective breeding approach, which is based on elevated plus-maze behavior and results in CD1-derived high (HAB), normal (NAB), and low (LAB) anxiety-related behavior mice. HAB mice displayed pronounced cued-conditioned fear compared to NAB/CD1 and LAB mice that coincided with increased phosphorylation of the protein kinase B (AKT) in the basolateral amygdala 45 min after conditioning. No similar changes were observed after non-associative immediate shock presentations. Fear extinction of recent but not older fear memories was preserved. However, HAB mice were more prone to relapse of conditioned fear with the passage of time. HAB mice also displayed higher levels of contextual fear compared to NAB and LAB mice and exaggerated avoidance following step-down avoidance training. Interestingly, HAB mice showed lower and LAB mice higher levels of acoustic startle responses compared to NAB controls. The increase in arousal observed in LAB mice coincided with the general absence of conditioned freezing. Taken together, our results suggest that the genetic predisposition to high anxiety-related behavior may increase the risk of forming traumatic memories, phobic-like fear and avoidance behavior following aversive encounters, with a clear bias towards passive coping styles. In contrast, genetic predisposition to low anxiety-related and high risk-taking behavior seems to be associated with an increase in active coping styles. Our data imply changes in AKT phosphorylation as a therapeutic target for the prevention of exaggerated fear memories.     

Why employees with higher challenging appraisals style are more affectively engaged at work? The role of challenging stressors: A moderated mediation model

Challenging stressors have been positively linked to various work outcomes. However, the role of individual differences in stress appraisal in shaping the function of challenging stressors and work outcomes has been rarely discussed. Drawing on the individual differences perspective, the authors propose that employees higher in challenge appraisal are more likely to have challenging stressors and are more responsive to such stressors to have a higher positive affect at work. Results obtained from 117 employees supported the hypotheses. The results indicated that challenge appraisal is positively related to challenging stressors. In addition, challenging stressors has a positive association with positive affect at work when challenge appraisal is high but has a null association when challenge appraisal is low. The findings suggest that challenging stressors does not necessarily bring positive work outcomes as suggested in past studies and highlight the importance of considering dispositional tendency in stress appraisal when looking into the function of challenging stressors and work outcomes.     

A behavioral approach to substance abuse prevention in the correctional setting: A preliminary report

This study evaluated the effectiveness of a substance abuse program in a correctional institution using social skills training for secondary prevention. Forty-four male inmates with a history of substance use participated in the pilot program. Program topics included drug, alcohol, and substance abuse treatment knowledge and development of anger and stress management skills. A pretest-posttest analysis revealed significant improvement in overall knowledge of program topics and within specific areas. Areas of greatest improvement were drugs and alcohol. Clients and group leaders reported that the program was effective in facilitating attitude and behavior change regarding substance abuse. Results suggest a social competence approach to substance abuse rehabilitation in correctional institutions holds promise for both increasing knowledge and teaching effective skills to resist future substance abuse.     

Unintended consequences of Ze Ren Zhi reforms in China: interplay of agricultural reform and population control policy

The aim of the discussion of unintended consequences of Ze Ren Zhi policy reforms in China is to show how isolating problems and developing solutions in isolation can lead to serious consequences. The Ze Ren Zhi reforms in 1978 were intended to increase agricultural productivity by changing from the collective system to an individual responsibility system, but the unintended and undesirable consequences were a growth in family size and discouragement of some environmentally sound land use practices. The prior system gave an equal share of collective income for an equal number of days worked. Under the new reform, "Baochan Daohu," each household had responsibility for a contracted quantity of grain production. Within 2-4 years, economic conditions improved considerably. A discussion is provided of the transition from rights and duties of the collectives to the new responsibility system and the experimentation with different systems. Specific attention is directed to land reforms, mutual aid teams, cooperatives, communes, variations of Ze Ren Zhi, contracting output to individual laborers, contracting jobs to households, and contracting output quotas to households. During the reforms, beginning in the 1950s and lasting until 1978, other changes were taking place. Death rates were declining and birth rates were increasing, such that in 1971 a campaign was established to promote the Late, Sparse, and Few policy for marrying and giving birth later, increasing birth intervals, and having fewer children. This voluntary program eventually took on a more universally mandatory nature. The 1950 Marriage Law stipulated 20 years as the legal age for marriage (18 years for females), and family planning (FP) workers during the 1970s were encouraging even later marriage, and by 1980 a system of rewards and penalties was established to reinforce small family size. After 1978 and a period of birth declines, the crude birth rate increased to 3.06 in 1983. The new responsibility system changed the reward and penalty system, led to a loss of FP workers, created conditions that gave advantages to large families, promoted early marriage and pregnancy, and created a migrant labor surplus. Chemical fertilizers were used and there was little incentive to get involved in reclamation or reforestation efforts that have longterm gain. Integrated planning and programming is needed for the short and long run.     

Nonunique solutions to the likelihood equation for the three-parameter logistic model

Samejima identified the possibility of multiple solutions to the likelihood equation (multiple maxima in the likelihood function) for estimating an examinee's trait value for the three-parameter logistic model. In the practical applications that Lord studied, he found that multiple solutions did not occur when the number of items was 20. In the present paper, fourteen multiple-choice achievement tests with from 20 to 50 items were examined to see if it was possible for them to produce item response vectors with multiple maxima; such vectors were found for all the tests. Examination of response vectors for large groups of real examinees found that from 0 to 3.1% of them had response vectors with multiple maxima. The implications of these results for multiple-choice tests are discussed.     

Independence of hand preference and sex-linked genetic effects on spatial performance.

The paper-and-pencil spatial performance of right- and left-handed high school students was compared separately for 1236 males and 1241 females. Handedness differences in favor of right-handed subjects were found among males only. Analysis of data for a subgroup of 555 subjects indicated that handedness and sex-linked genetic effects acted independently and additively on spatial performance.
