A longitudinal study evaluated associations between intimacy and relational uncertainty and characteristics of interdependence within nonmarital romantic relationships. Three hundred and fifteen college students in the United States completed a Web‐based survey about their relationship weekly for 6 weeks. Results indicated nonlinear associations between intimacy and relational uncertainty and perceptions of a partner’s interference (p < .001) that were inconsistent with hypotheses. Intimacy was positively associated with a partner’s influence in and facilitation of activities (p < .001). An interaction between intimacy and a partner’s influence predicted a partner’s interference, such that a partner’s influence was more positively associated with interference at low, compared to high, intimacy (p < .05). The implications of these findings for rethinking the relational turbulence model are discussed.  相似文献

This study was designed to measure what effect the establishment of a parent-counselor relationship prior to the child's entrance into junior high school would have upon the child's adjustment to school and parent-child communication. Subjects were students and parents from Lealman Junior High School in St. Petersburg, Florida. Parents of the experimental group had a one-hour individual conference with the school counselor prior to the child's entrance into junior high school. Experimental and control groups were followed over a three-year period. The experimental group showed significantly greater (p < .001) parental contact with the school, significantly better student attendance (p < .001), and significantly higher grade point averages (p < .001) than the control group. This was accompanied by a lower dropout rate (p < .05) and fewer disciplinary referrals (p < .001). An overall more effective use of school counselors and other school personnel resulted.  相似文献

The study aims to investigate the quality of life (QOL) and the psychological situation in Chinese patients with rosacea. A total of 196 healthy controls and 201 rosacea patients were involved in the final analysis. The general information, the Dermatology Life Quality Index (DLQI) and the Hospital Anxiety and Depression Scale (HADS) were collected. Significantly higher DLQI, anxiety and depression score were observed in the rosacea group compared to the control group (p < .01). Total DLQI score of patients was positively related with anxiety (r = .526, p < .001) and depression scores (r = .399, p < .001) in HADS. Rosacea had significant psychological impact on Chinese patients and had substantial influence on their QOL. Physicians should address the psychosocial needs of rosacea patients as much as its physical symptoms.  相似文献

This study examines the effects of exposure to the muscular male body ideal on body-focused negative affect among male gym users and non-exercisers. As hypothesized, the impact of media exposure depended on men's exercise status. Non-exercisers (n = 58) reported greater body-focused negative affect after exposure to images of muscular male models than after neutral images (no model controls), whereas gym users (n = 58) showed a tendency for less body-focused negative affect after the model images than after the control images. Furthermore, the extent to which gym users were motivated to increase strength and muscularity moderated these exposure effects; men who reported stronger strength and muscularity exercise motivation reported a greater degree of self-enhancement after exposure to the muscular ideal. The findings are interpreted with respect to likely differences in motives for social comparisons.  相似文献

Much recent research using discrete unimanual tasks has indicated that individuals with Down syndrome (DS) have more difficulty performing verbal-motor tasks as compared to visual-motor tasks (see Perceptual-Motor Behavior in Down Syndrome, Human Kinetics, Champaign, IL, 2000, p. 305 for a review). In continuous tasks, however, individuals with DS perform better when movement is guided by auditory information compared to visual information (Downs Syndr.: Res. Prac. 4 (1996) 25; J. Sport Exercise Psy. 22 (2000) S90). The aim of the present study was to investigate if there are any differences for adults with DS between visual, auditory and verbal guidance in a continuous bimanual task. Ten adults with DS, 10 adults without DS and 10 typically developing children drew lines bimanually towards the body (down) and away from the body (up) following three different guidance conditions: visual (flashing line), auditory (high tone, low tone), and verbal (“up”, “down”). All participants produced mostly in-phase movements and were close to the 1000 ms target time for all guidance conditions. The adults with DS, however, displayed greater variability in their movement time, movement amplitude and bimanual coordination than adults without DS. For all groups, the left hand was slower and more variable in producing the lateral movements than the right hand. The results regarding guidance information suggest that auditory information is beneficial for repetitive bimanual tasks for adults with DS. Possible mechanisms that cause these results will be discussed.  相似文献

Only a very few studies on the effects of cold on human information processing appear to exist. Therefore, the present experiment was designed to study the effects of the experimentally induced lowering of body core temperature on information processing, while applying a reaction time paradigm. Thirty healthy male volunteers performed a stimulus evaluation—response selection reaction time task after exposure to ambient temperatures of either 28 or 5°C. A 0.5°C-decrease in body core temperature resulted in a significant increase in both reaction and movement time indicating a general deteriorating effect of lowering of body core temperature on information processing. Mean reaction times were 538 ms and 549 ms for the control and the cold group, respectively (p<.05). The respective mean movement times were 298 ms and 269 ms (p<.001). Speed of stimulus evaluation was not sensitive to decreases in body core temperature. However, response complexity and body core temperature showed a significant interaction in their effect on movement time (p<.05), indicating that lowering of body core temperature is more likely to affect response-related stages of central information processing rather than stimulus evaluation. Furthermore, movement time appeared to be more sensitive to cold-induced effects on information processing as compared to reaction time. Additional correlational analyses suggest that the observed effects can be considered as independent of changes in skin temperature and experienced levels of thermal discomfort. Taken together, the results indicate that lowering of body core temperature differentially affects various stages of information processing.  相似文献

This experiment was designed to isolate the incentive properties of uncertainty reduction (information) from those of material reward value and variety in a binary, competitive reward situation. After pretraining, fourth-grade children chose between a prescaled high-reward object and a question mark stimulus which concealed one of two lower-valued objects on each of 40 trials. The concealed objects appeared equally often for half the Ss and with a 9:1 ratio for the rest, thus, reducing one or 47 bit of uncertainty, respectively, when chosen. Ss also served as their own controls. In the control condition, stimulus color cued the identity of the concealed object, reducing uncertainty before a choice was made. As predicted, significantly more question marks were chosen when such choice reduced uncertainty (p < .001). Evidence for the influence of relative-reward value and object novelty was obtained. Uncertainty reduction appears to have incentive value independent of other factors.  相似文献

Knee rehabilitation exercises to improve motor control, target movement fluency, and displacement variability. Although knee movement in the frontal plane during exercise is routinely assessed in clinical practice, optimal knee control remains poorly understood. In this study, 29 healthy participants (height: 1.73 ± 0.11 m, mass: 73.5 ± 16.4 kg, age: 28.0 ± 6.9 years) performed 4 repetitions of 5 rehabilitation exercises while motion data were collected using the VICON PlugInGait full-body marker set. Fluency and displacement variability were calculated for multiple landmarks, including center of mass (CoM) and knee joint centers. Fluency was calculated as the inverse of the average number of times a landmark velocity in the frontal plane crossed zero. Variability was defined as the standard deviation of the frontal plane movement trajectories. CoM fluency and displacement variability were significantly different between tasks (p < .001). CoM displacement variability was consistently smallest compared to the constituent landmarks (p < .005). This was interpreted as a whole body strategy of compensatory variability constraining CoM frontal plane movement. Ipsilateral knee fluency (p < .01) and displacement variability (p < .001) differed substantially between tasks. The role of the weight-bearing knee seemed dependent on task constraints of the overall movement and balance, as well as constraints specific for knee joint stability.  相似文献

Sixty-five undergraduates were assigned to guide a blindfolded confederate through a floor maze. The frequency of touching the confederate's skin and the length of time required to complete the trip through the maze were recorded. Each subject was also given a self-administered Rorschach test; an independent count was made of the number of oral responses given. Orality was positively related to touching behavior (r=.39, p=.001) and with speed of guiding the confederate through the maze (r=.31, p=.01).  相似文献

The purpose of this study was to examine differences in self-reported dispositional forgiveness types among older male prison inmates who experienced parental separation/divorce earlier in life. Participants included a sample of N = 261 incarcerated men, aged 45 and older, residing in state-managed prisons in Oklahoma. IBM/SPSS 22.0 was used to examine mean differences across forgiveness of self, situation, and others. Significant mean differences were evident only for forgiveness of situation. In particular, significant differences emerged relative to depressive affect F (1, 192) = 19.90, p < .001, and social support F (1, 192) = 18.64, p < .001. After controlling for age, race, religiosity, depression, social support, perceived health, crime type, and parental separation/divorce, one significant interaction (crime type X parental separation/divorce) emerged, F (1, 192) = 4.42, p < .05. It appears that the disposition to forgive the situation among older prison inmates depends on criminal offender type as well as whether the older inmate experienced parental dissolution earlier in life. Implications for pastoral counseling programing and forgiveness therapy treatment for older male prison inmates who experienced parental separation/divorce earlier in life are discussed.  相似文献

We previously showed (Bernstein, Santelli, Alter-Reid, & Androsiglio, 1985) pursuing and distancing to be semi-independent constructs sharing variance with the Rathus Assertiveness Scale (Rathus, 1973), the Zuckerman Sensation-Seeking Scale, Form V (Zuckerman, Eysenck, & Eysenck, 1978), the Eysenck Personality Inventory (EPI; Eysenck & Eysenck, 1968) extraversion score, and the Bem Sex Role Inventory (Bem, 1974). This study extends our findings by administering these scales and Rotter's Internal-External Locus of Control Scale (Rotter, 1966) to a sample of 203 Indians and 161 Thais (all were English speaking and primarily students at universities where instruction is in English). Our original findings were supported. We also found that locus of control and the EPI neuroticism score are significantly related (p < .05) to pursuing and distancing in our Eastern samples. In general, our Eastern subjects pursued less and distanced more (p < .05). Although unrelated to pursuing or distancing, in general, our Eastern subjects were more androgynous (p < .001) than our American sample.  相似文献

ABSTRACT. Motor disorders may occur in mild cognitive impairment (MCI) and at early stages of Alzheimer's disease (AD), particularly under divided attention conditions. We examined functional mobility in 104 older adults (42 with MCI, 26 with mild AD, and 36 cognitively healthy) using the Timed Up and Go test (TUG) under 4 experimental conditions: TUG single task, TUG plus a cognitive task, TUG plus a manual task, and TUG plus a cognitive and a manual task. Statistically significant differences in mean time of execution were found in all four experimental conditions when comparing MCI and controls (p < .001), and when comparing MCI and AD patients (p < .05). Receiver-operating characteristic curve analyses showed that all four testing conditions could differentiate the three groups (area under the curve > .8, p < .001 for MCI vs. controls; area under the curve > .7, p < .001 for MCI vs. AD). The authors conclude that functional motor deficits occurring in MCI can be assessed by the TUG test, in single or dual task modality.  相似文献

This study examined whether an alteration in the effort–reward relationship, a theoretical framework based on cognitive neuroscience, could explain cognitive fatigue. Forty persons with MS and 40 healthy age- and education-matched cognitively healthy controls (HC) participated in a computerized switching task with orthogonal high- and low-demand (effort) and reward manipulations. We used the Visual Analog Scale of Fatigue (VAS-F) to assess subjective state fatigue before and after each condition during the task. We used mixed-effects models to estimate the association and interaction between effort and reward and their relationship to subjective fatigue and task performance. We found the high-demand condition was associated with increased VAS-F scores (p < .001), longer response times (RT) (p < .001) and lower accuracy (p < .001). The high-reward condition was associated with faster RT (p = .006) and higher accuracy (p = .03). There was no interaction effect between effort and reward on VAS-F scores or performance. Participants with MS reported higher VAS-F scores (p = .02). Across all conditions, participants with MS were slower (p < .001) and slower as a function of condition demand compared with HC (p < .001). This behavioural study did not find evidence that an effort–reward interaction is associated with cognitive fatigue. However, our findings support the role of effort in subjective cognitive fatigue and both effort and reward on task performance. In future studies, more salient reward manipulations could be necessary to identify effort–reward interactions on subjective cognitive fatigue.  相似文献

Functional movements (FMs) dysfunction is a potential risk factor of injuries. A variety of training strategies is proposed to improve the performance of FMs. We investigated if a system of fundamental movement exercises called Dynamic Neuromuscular Stabilization (DNS) could improve FMs. Thirty-four female students were randomly assigned into two matched groups to receive DNS (the study protocol) versus physical fitness (PF) training. The groups practiced for six-weeks (three sessions of 50 min weekly). We used five FMs tests as pre and post measures of exercise effectiveness. Repeated Measures ANOVA showed a significant interaction in all five FMs tests in favour of DNS group (F(1,32) ≥ 4.13, P ≤ .001 and ƞ2 ≥ 0.29), meaning that DNS group had a higher progress rate compared to that of PF group. Based on Eta-square coefficients, the highest and lowest differences in the progression rate were observed in Y-Balance and Functional Movement Screening Tests, respectively. Our findings supported the hypothesis that fundamental movements of DNS could be used to improve FMs. However, the progression coefficient declined as FMs became more specific. Lower progression of “specific FMs” suggests that it might prove more effective to add “specific training” to “fundamental training” for them.  相似文献

Maltreated children in out-of-home care are at high risk for poor relationships with caregivers (i.e., biological parents and substitute caregivers) and high levels of internalizing symptoms. It is unclear if these poor relationships are related to, and account for a large portion of the variance in maltreated children’s internalizing symptoms, above and beyond maltreatment type and out-of-home care factors. This study examined the relation between attachment quality with both biological parents and substitute caregivers and children’s internalizing symptoms within a sample of 493 maltreated children (aged 9–11; 51.0?% male) recently placed in out-of-home care. A series of hierarchical regression models indicated that greater child-reported attachment quality with both biological parents and substitute caregivers was associated with fewer child-reported anxiety (β?=??.15, p?<?.01; β?=??.29, p?<?.001, respectively) and depression symptoms (β?=??.14, p?<?.01; β?=??.28, p?<?.001, respectively) as well as fewer child internalizing symptoms (β?=??.12, p?<?.05; β?=??.14, p?<?.01, respectively). Attachment quality with the biological parent and substitute caregiver each explained a significant proportion of the variance in children’s internalizing symptoms, above and beyond child demographics, maltreatment type, and out-of-home care variables. The study also examined whether children’s attachment with substitute caregivers moderated the relationship between children’s attachment with biological parents and children’s internalizing symptoms. No statistically significant moderation effects were found. Future clinical work should focus on enhancing attachment quality between children and both biological parents and substitute caregivers, as these relationships appear to individually relate to the children’s internalizing symptomology.  相似文献

Many studies have used mirror-image stimulation in attempts to find self-recognition in monkeys. However, very few studies have presented monkeys with video images of themselves; the present study is the first to do so with capuchin monkeys. Six tufted capuchin monkeys were individually exposed to live face-on and side-on video images of themselves (experimental Phase 1). Both video screens initially elicited considerable interest. Two adult males looked preferentially at their face-on image, whereas two adult females looked preferentially at their side-on image; the latter elicited lateral movements and head-cocking. Only males showed communicative facial expressions, which were directed towards the face-on screen. In Phase 2 monkeys discriminated between real-time, face-on images and identical images delayed by 1 s, with the adult females especially preferring real-time images. In this phase both screens elicited facial expressions, shown by all monkeys. In Phase 3 there was no evidence of discrimination between previously recorded video images of self and similar images of a familiar conspecific. Although they showed no signs of explicit self-recognition, the monkeys’ behaviour strongly suggests recognition of the correspondence between kinaesthetic information and external visual effects. In species such as humans and great apes, this type of self-awareness feeds into a system that gives rise to explicit self-recognition.  相似文献

Fat talk, dialogues among women involving negative body-focused discussions, was studied as a function of conformity and social likeability through the use of four vignettes depicting young women in conversation. Using a 2 (body presentation style of the group: negative or positive) × 2 (body presentation style of the target, Jenny: negative or positive) factorial design, 215 college women (92.1% non-Hispanic Caucasian) read one of four vignettes in a classroom setting and made ratings on a social likeability scale. Participants’ personal ratings of Jenny's likeability were higher when she spoke positively about her body, whereas they expected the other group members in the vignette to like Jenny more when she conformed to the group's body presentation style. This study is the first to support two competing norms for women's body image—the existing norm to fat talk versus a newly documented norm that some women like others who express body acceptance.  相似文献

Investigated the effects of fear arousal and sidedness variables on compliance with a dietary regimen. Experiments involved 202 women volunteers who were 10 per cent or more overweight, and aged 20-60 years. Experiment 1 involved a 3 (low, medium, high fear) × 2 (single, multiple exposure to fear message) × 2 (one-, two-sided communication) design. The fear levels involved discussing the health hazards of obesity. Experiment 2 manipulated the fear-message position relative to the recommendations (fear-recommendations, recommendations-fear, fear-delay-recommendations). Persuasive impact was measured via follow-up weight checks at 2, 4, 8, and 16 weeks. Results indicate nonsignificant effects from sidedness and pre-standardised fear levels. Using subjects' fear arousal ratings medium fear is significantly better (p < .025), supporting Janis's curvilinear hypothesis. A single exposure to the fear message is superior (p < .025) to multiple exposures, the interaction with time being highly significant (p < .001). Experiment 2 results indicate the optimum position for the fear message as immediately prior to recommendations (p < .025). Results support both cognitive and fear-reduction hypotheses, but the latter is favoured.  相似文献

Family factors and the media have been established as determinants of body satisfaction, yet little research has looked at the contribution of spousal influence in body dissatisfaction. Marital quality and satisfaction can be a protective factor in the health of women, while high rates of criticism have been associated with poorer health outcomes. The present study investigated the relationship between perceptions of family and spousal factors and body dissatisfaction in married women. Additionally, the impact of marital communication was investigated. Seventy-seven married women completed self-report questionnaires assessing familial body-focused comments, spousal evaluation of a wife’s body, marital communication patterns, and body dissatisfaction. After controlling for weight status, women’s perceptions of familial body-focused comments and spousal evaluation emerged as significant predictors of body dissatisfaction. It was also found that more destructive communication patterns moderated the effect of perceived spousal evaluation on body dissatisfaction. This study provides some context for understanding the impact of specific influences on women’s body dissatisfaction.  相似文献

This effort argues for an augmented version of the relatively new Risk Information Seeking and Processing (RISP) Model, and subsequently applies this augmented RISP model specifically to environmental risk information seeking. Nearly 830 randomly selected members of a national panel were surveyed about their attitudes, perceptions, and behaviors regarding seeking information about an environmental risk—global warming. Path analysis suggests the promise of applying an augmented RISP model to environmental risk information seeking (R2 = .72 for information seeking intent) and reinforces prior research, which indicated the notable contribution that perceived social pressures may have when individuals seek such information (β = .68, p < .001).  相似文献
