Dependence of Finger Flexion Force on the Posture of the Nonperforming Fingers During Key Pressing Tasks

In visuomotor tasks that involve accuracy demands, small directional changes in the trajectories have been taken as evidence of feedback-based error corrections. In the present study variability, or intermittency, in visuomanual tracking of sinusoidal targets was investigated. Two lines of analyses were pursued: First, the hypothesis that humans fundamentally act as intermittent servo-controllers was re-examined, probing the question of whether discontinuities in the movement trajectory directly imply intermittent control. Second, an alternative hypothesis was evaluated: that rhythmic tracking movements are generated by entrainment between the oscillations of the target and the actor, such that intermittency expresses the degree of stability. In 2 experiments, participants (N = 6 in each experiment) swung 1 of 2 different hand-held pendulums, tracking a rhythmic target that oscillated at different frequencies with a constant amplitude. In 1 line of analyses, the authors tested the intermittency hypothesis by using the typical kinematic error measures and spectral analysis. In a 2nd line, they examined relative phase and its variability, following analyses of rhythmic interlimb coordination. The results showed that visually guided corrective processes play a role, especially for slow movements. Intermittency, assessed as frequency and power components of the movement trajectory, was found to change as a function of both target frequency and the manipulandum's inertia. Support for entrainment was found in conditions in which task frequency was identical to or higher than the effector's eigenfrequency. The results suggest that it is the symmetry between task and effector that determines which behavioral regime is dominant.     

Creativity to Sexual Values as Factors of Importance,Frequency, and Feeling Ratings

Factor analyses identified one General and 23 Primary factors, grouping independently the dimensions of importance (attitudinal), frequency (of experiences), and pleasantness-unpleasantness (of bodily feelings) for 48 items that broadly reflect human values, activities, and feelings such that they are applicable cross-culturally. This Specific Value Scale was self-rated by 296 college students whose 13 “Values” (incorporating the three dimensions) ranged from Social Activities and Ethical Beliefs to Sexual Activities and Significance (importance feeling), these values being also reflected in factors. The importance of self-understanding and the pleasantness of clothes grooming and of friendship were emphasized. Deemphasized were rebelling, arguments, and negative feelings. No significant differences were found between the sexes.     

Affect Dysregulation in Individuals With Borderline Personality Disorder: Persistence and Interpersonal Triggers

We hypothesized that affect dysregulation among individuals with borderline personality disorder (BPD) would involve greater persistence of negative affect between interpersonal events and heightened reactivity to stimuli indicating risk of rejection or disapproval, specifically perceptions of others’ communal (agreeable-quarrelsome) behaviors. A total of 38 participants with BPD and 31 controls collected information about affect and perceptions of the interaction partner's behavior during interpersonal events for a 20-day period. Negative and positive affect persisted more across interpersonal events for individuals with BPD than for controls. In addition, individuals with BPD reported a greater increase in negative affect when they perceived less communal behavior and a smaller increase in positive affect when they perceived more communal behavior in others. Findings indicate the importance of interpersonal perceptions in the affect dysregulation of individuals with BPD.     

Competition and men’s face preferences

Several studies have examined potentially adaptive shifts and sources of individual differences in women’s face preferences, but relatively few studies have looked for similar findings in men. Evidence suggests that men of higher mate-value may be better placed to compete for relationships with higher-quality women, and that contest competition may influence men’s perceptions of dominance. Here, we looked at the effects of winning/losing in male–male competition on men’s face preferences. Participants were randomly and unknowingly assigned to either win or lose the first-person shooter video game Counter-Strike: Source against an unseen male confederate who could control the outcome through game cheats. We found that, compared to men assigned to the losing condition, men assigned to the winning condition had significantly (p = 0.012) higher preferences for women’s facial femininity. Results suggest that the outcomes of male–male competition may alter men’s mate preferences.     

Suppressor effects and age differences in the expression of anxious emotion

This study examined the role of suppressor effects on age differences in anxious emotion. Children and adolescents (n = 1099) ages 7–18 years were assessed for separation anxiety, social anxiety, and generalized anxiety. Results of zero-order correlations indicated a significant negative association between age and separation anxiety but no association for social anxiety and generalized anxiety. However, semi-partial correlations indicated the presence of a cooperative suppressor effect such that the associations between age and social anxiety as well as age and generalized anxiety symptoms became significant and positive and the association with separation anxiety became larger in a simultaneous regression analysis of each facet with age. Similar effects occurred when controlling for hyperarousal in an ANCOVA across grade levels. Results suggest that attempts to understand developmental differences in anxious emotion in childhood and adolescence will be facilitated by parsing facets of anxious emotion and attention to potential suppressor effects.     

Personality and social attitudes: Evidence for positive-approach motivation

Extensive research has linked general personality factors to social attitudes, but there has been comparatively little work on the roles played by specific approach-avoidance personality factors, especially positive-approach ones. Here we relate such factors to the two main clusters of social attitudes (Right-Wing Authoritarianism, RWA; and Social Dominance Orientation, SDO), and related cognitive constructs (Need for Cognition and Need for Closure). Results revealed: (a) positive-approach motivation is consistently related to both RWA and SDO, with little contribution from negative-avoidance motivation; and (b) negative-avoidance motivation played a part in Need for Cognition (negatively related) and Need for Closure (positively related). These data challenge previous theorizing concerning the role of fear/anxiety in social attitude formation and prejudice more generally. We conclude that, to a larger extent than previously thought, approach-related personality factors underpin the positive reinforcement of social attitudes and prejudice. Our results may help to account for the failure of programmes designed to reduce prejudice which have been based on the reduction of negative emotion and motivation.     

Mother-blaming in family therapy: An empirical investigation

Abstract

This study tested two hypotheses derived from the feminist critique of family therapy in a sample of AAMFT members. The stimulus was a brief vignette of an initial therapy session with a family presenting a teen-aged child as the identified patient. It was hypothesized that family therapists would rate the mothers in the vignette as more dysfunctional than fathers. It was also hypothesized that mothers would be asked to bear more of the burden of change in treatment plans written by subjects. Neither hypothesis was supported. However, respondents did rate the concerned parent, regardless of sex, as more dysfunctional. Since this is a role often occupied by women, this finding may indicate some gender bias.     

Reduced willingness to approach genuine smilers in social anxiety explained by potential for social evaluation,not misperception of smile authenticity

ABSTRACT

We investigate perception of, and responses to, facial expression authenticity for the first time in social anxiety, testing genuine and polite smiles. Experiment 1 (N?=?141) found perception of smile authenticity was unaffected, but that approach ratings, which are known to be reduced in social anxiety for happy faces, are more strongly reduced for genuine than polite smiles. Moreover, we found an independent contribution of social anxiety to approach ratings, over and above general negative affect (state/trait anxiety, depression), only for genuine smiles, and not for polite ones. We argue this pattern of results can be explained by genuine smilers signalling greater potential for interaction – and thus greater potential for the scrutiny that is feared in social anxiety – than polite smiles. Experiment 2 established that, relative to polite smilers, genuine smilers are indeed perceived as friendlier and likely to want to talk for longer if approached. Critically, the degree to which individual face items were perceived as wanting to interact correlated strongly with the amount that social anxiety reduced willingness to approach in Experiment 1. We conclude it is the potential for social evaluation and scrutiny signalled by happy expressions, rather than their positive valence, that is important in social anxiety.     

Emotion,core affect,and psychological construction

As an alternative to using the concepts of emotion, fear, anger, and the like as scientific tools, this article advocates an approach based on the concepts of core affect and psychological construction, expanding the domain of inquiry beyond “emotion”. Core affect is a neurophysiological state that underlies simply feeling good or bad, drowsy or energised. Psychological construction is not one process but an umbrella term for the various processes that produce: (a) a particular emotional episode's “components” (such as facial movement, vocal tone, peripheral nervous system change, appraisal, attribution, behaviour, subjective experience, and emotion regulation); (b) associations among the components; and (c) the categorisation of the pattern of components as a specific emotion.
