Improving work motivation and performance in brainstorming groups: The effects of three group goal-setting strategies

An experiment was conducted with 30 groups (n = 120) solving brainstorming tasks under four different group goal conditions: do your best (DYB), directive group goal setting (DGGS), participative group goal setting (PGGS), and PGGS in combination with individual goal setting (PGGS + IGS). As expected, all groups with specific and difficult group goals performed better than DYB control groups. It is hypothesized that these positive effects of group goal setting on brainstorming performance arise because group goal setting counteracts motivation losses such as social loafing. In addition, group goal setting should promote motivation gains arising from social compensation and related cognitive processes, in particular high identification with the group. Consistent with this hypothesis, it was found that group goal setting increased team identification, the readiness to compensate for other weak group members, the value of group success, and the value of group failure. Mediation analysis also indicated that concern to avoid group failure was partly responsible for performance improvements. Finally, no large differences were found between PGGS + IGS and PGGS or DGGS. On this basis group goal setting can be considered a robust strategy for improving work motivation and brainstorming performance in groups.     

Counselor and client personality as determinants of counselor expectancy effects

Seventy-eight students enrolled in summer-session college courses were randomly assigned to serve either as counselors or as clients for a 20-min, role-played peer counseling session. All of the subjects completed a battery of standardized personality measures. Each counselor interacted with two clients. Prior to the sessions, the counselor was led to believe that one of the clients was especially introverted and that the other client was especially extraverted. Dependent measures were based on clients' change scores on a mood adjective rating scale administered before and after the peer counseling sessions. Analyses showed that counselors who were more successful at biasing their clients in the direction of their expectancies (a) scored higher on measures of Dogmatism, Nurturance, and Social Recognition, (b) scored lower on Impulsivity, and (c) were more likely to be women. Clients who were more susceptible to counselor bias scored higher on the Self-Monitoring Scale, the Self-Monitoring Other-Directedness subscale, and Social Recognition. These results are discussed in light of previous research and their implications for research on interpersonal expectancy effects.     

Leadership style and role differentiation as determinants of group effectiveness

All-male and all-female groups discussed a case history and provided a statement of their analysis of the case The relationship between leadership style, as measured by Fiedler's Least Preferred Co-worker (LPC) instrument, and task effectiveness (quality of the statement) was investigated for both the top task contributor and the best-liked member of the group LPC of the top task contributor did not relate to task effectiveness. In the role-differentiated groups, LPC of the best-liked member related positively to task effectiveness in the male groups (p < .05) and negatively in the female groups (p < .01) For the male groups, questionnaire data were consistent with the interpretation that the relationship between LPC of the best-liked member and task effectiveness was mediated by the ability of the high-LPC best-liked member to reduce interpersonal tension that interfered with task effectiveness. LPC of die best-liked member of the female groups was related to intermember attraction LPC did not affect role recruitment.     

控制幻觉与人格、动机关系研究

目的本研究考察了人格、动机强弱分别与心理控制幻觉之间的关系。方法采用被试内实验设计的方法,用艾森克人格问卷进行测量。结果与结论动机水平的高低与控制幻觉的形成之间存在明确的关系,即前后动机水平的发生变化,信心分差异显著(t=-3.1,p=0.006<0.05),动机越强则产生控制幻觉的倾向性越大;人格中的外倾性,精神质与心理控制幻觉的产生存在显著的正相关(r=0.766,P<0.01;r=0.827,P<0.01);外倾性这一心理特质对控制幻觉的产生有较强的预测作用。     

Runaway girls in distress: motivation, background, and personality.

This paper deals with girls aged 13 to 21 who have run away from home. Social workers who work with such girls point out that they are not a homogeneous population and that their motives can be very different. This study divides their motives for running away into two types, "running from" and "running to," and describes the specific personality traits associated with each. Findings indicate that girls who "run to" are younger, more impulsive, have an internal locus of control and a history of more runaways and longer periods of staying away from home. Girls who "run from," on the other hand, are older, more reflective, have an external locus of control and a history of fewer runaways and shorter periods away from home.     

Modeling the personality of dyads and groups

The paper presents a methodological approach for assessing the personality of a dyad or a group, a concept that is not equivalent to the sum, or mean, of the individual scores. We illustrate how the logic of the multitrait multimethod approach, which is a familiar technique for establishing construct validity, can be extended to assess the construct of a relationship "personality." The model, which we call the latent group model, provides a decomposition and comparison of individual-level and group-level variance in a given trait, and the individual-level and group-level covariance or correlation between two traits. The model is also extended to the assessment of stability of the individual and group level traits. Throughout the paper, we draw connections between related methods and show how the latent group model can be estimated through hierarchical linear modeling.     

Neurobiology of the structure of personality: dopamine, facilitation of incentive motivation, and extraversion

Extraversion has two central characteristics: (1) interpersonal engagement, which consists of affiliation (enjoying and valuing close interpersonal bonds, being warm and affectionate) and agency (being socially dominant, enjoying leadership roles, being assertive, being exhibitionistic, and having a sense of potency in accomplishing goals) and (2) impulsivity, which emerges from the interaction of extraversion and a second, independent trait (constraint). Agency is a more general motivational disposition that includes dominance, ambition, mastery, efficacy, and achievement. Positive affect (a combination of positive feelings and motivation) is closely associated with extraversion. Extraversion is accordingly based on positive incentive motivation. Parallels between extraversion (particularly its agency component) and a mammalian behavioral approach system based on positive incentive motivation implicate a neuroanatomical network and modulatory neurotransmitters in the processing of incentive motivation. A corticolimbic-striatal-thalamic network (1) integrates the salient incentive context in the medial orbital cortex, amygdala, and hippocampus; (2) encodes the intensity of incentive stimuli in a motive circuit composed of the nucleus accumbens, ventral pallidum, and ventral tegmental area dopamine projection system; and (3) creates an incentive motivational state that can be transmitted to the motor system. Individual differences in the functioning of this network arise from functional variation in the ventral tegmental area dopamine projections, which are directly involved in coding the intensity of incentive motivation. The animal evidence suggests that there are three neurodevelopmental sources of individual differences in dopamine: genetic, "experience-expectant," and "experience-dependent." Individual differences in dopamine promote variation in the heterosynaptic plasticity that enhances the connection between incentive context and incentive motivation and behavior. Our psychobiological threshold model explains the effects of individual differences in dopamine transmission on behavior, and their relation to personality traits is discussed.     

Review, critique, and synthesis of personality theory in motivation to sexually assault

A widely-cited meta-analysis of recidivism amongst adult male perpetrators or sexual assult [Hanson and Bussiere, J. Consult. Clin. Psychol. 66 (1998) 348–362] found that the presence of any personality disorder (APA, Diagnostic and Statistical Manual of Mental Disorders: DSM-III-R. (1987); [APA, Diagnostic and Statistical Manual of Mental Disorders: DSM-IV (1994)] was the only variable to significantly predict sexual recidivism in a category measuring “Psychological Maladjustment” (r₊=.16, n=315). The relationship between personality disturbance and new sexual offenses is undoubtedly a dynamic relationship that deserves exploration. This review and critique of theory covers two theories of personality: (1) a psychoanalytic theory of rapist personality offered by Groth [Men Who Rape: The Psychology of the Offender. (1979), New York: Plenum] and (2) a general biosocial theory or personality disturbance offered by Millon [Disorders of Personality: DSM-IV and Beyond. (1996). New York: Wiley]. Theory offered by Groth is critiqued and limitations considered. Theory offered by Millon is offered and the two approaches are synthesized to suggest possible causes of characteristic psychological disturbance associated with perpetration of sexual assault. Applications for research and practice are considered, and implications of this line of research for risk assessment and sexual assault prevention are reviewed.     

Intrinsic motivation, extrinsic motivation, and learning English as a foreign language

The objective of this study was to examine the relationships of amotivation, extrinsic motivation, and intrinsic motivation with learning the English language. The 230 Iranian students at Shiraz University were tested using the Language Learning Orientations Scales to measure Amotivation, Extrinsic Motivation, and Intrinsic Motivation as explanatory variables. Grade point average in English exams was selected as a measure of English learning Achievement. Multiple regression analysis revealed that learning Achievement scores were predicted by scores on the Amotivation subscale, Introjected Regulation subscale, Knowledge subscale, and Stimulation subscale, whereas, the External and Identified Regulation and Accomplishment subscales did not have a significant relationship with Achievement. The results are discussed in terms of differences in Iranian context and culture.
