In this article, I reflect upon my own career to distil some general recommendations for doing high‐impact social psychological research in the midst of a worldwide pandemic. My suggestions include (a) testing and deriving theories that can help explain real‐world human judgment and behaviour (answering questions that people care about), (b) preaching beyond the choir (communicating your research to audiences outside of social psychology), and (c) birds of a feather are stronger together (maximizing impact through strategic collaborations). 相似文献

Developmental dyslexia (DD), a severe and frequent disorder of reading acquisition, is characterized by a diversity of cognitive and motor deficits whose interactions still remain under debate. Although deficits in the automatization of sensorimotor control have been highlighted, internal action representation allowing prediction has never before been investigated. In this study, we considered action representation of 18 adolescents with pure DD and 18 age-matched typical readers. Participants actually and mentally performed a visually guided pointing task involving strong spatiotemporal constraints (speed/accuracy trade-off paradigm). While actual and mental movement times of typical readers were isochronous and both conformed to Fitts’ law, the movement times of dyslexics differed between conditions, and only the actual movement times conformed to Fitts’ law. Furthermore, the quality of motor imagery correlated with word reading abilities. This suggests that the process of action representation is impaired in pure DD and supports the sensorimotor perspective of DD. Theoretical implications are discussed. 相似文献

Large electrolytic lesions were placed in the midbrain central gray of male rats. Their effects on hypothalamically induced aggression, switch-off behaviour, and locomotion were investigated. A number of these animals were also tested for territorial intermale aggression in order to compare electrically induced and spontaneous aggression. Large lesions resulted in an increase of the current threshold to induce aggression by hypo-thalamic stimulation. Smaller, but still quite large, lesions decreased the threshold current for hypothalamic aggression. After the operation a decrease in the threshold for switch-off was present, both in the experimental and the control group. Current thresholds for locomotion were decreased after the lesions only in the experimental group. Spontaneous aggression was temporarily decreased after the lesion. No indication was found that other behavioural elements of the animal were distorted by the lesion. The parallel between the effects on spontaneous and electrically induced aggression makes it attractive to ascribe a role to the neural circuit of hypothalamus and central gray in territorial aggression. However, even with large lesions the animals were still capable of fighting, hence the central gray is not indispensable. An attempt was made to explain the differential effects that differently sized central gray lesions have on hypothalamic aggression. 相似文献

The question investigated in this study is how the temperament traits of strength of excitation (SE), strength of inhibition (SI), and mobility (MO) affect behaviour during the execution of computer tasks and tasks interrupting them. Several hypotheses, partly derived from the regulative theory of temperament, were tested in an experiment in which the natural environment and the types of task commonly performed by secretaries were simulated. The sample consisted of 39 female secretaries (21–64 years old). It was found that individuals high on SE and MO needed less time to resume tasks after an interruption than individuals low on these temperament traits. Interruptions similar to the main task resulted in longer resumption times for low-SE individuals. MO was negatively related to the time needed to perform the main task. A model describing the relationship between the frequency of switches between tasks and the speed of task performance in low-MO and high-MO individuals is presented. 相似文献

Outgroups are usually viewed with suspicion and expected to discriminate against the ingroup. The present study demonstrated that ingroup members attributed past discriminatory behaviour committed by individuals of unknown group membership more to outgroup members than to either ingroup members or members of a neutral group. In contrast, past egalitarian behaviour was attributed less to outgroup members than to members of a neutral group. Ingroup members also expected more discrimination from a future outgroup allocator than from a future neutral group allocator. Finally, the study showed that ingroup members' own behaviour in allocating money became more biased in favour of ingroup members vis-á-vis outgroup members when the future allocator was from an outgroup rather than from a neutral group and when they had witnessed the discriminatory behaviour of an allocator in the past. 相似文献

People are reluctant to harm some people in order to help others, even when the harm is less than the forgone help (the harm resulting from not acting). The present studies use hypothetical scenarios to argue that these judgments go against what the subjects themselves would take to be the best overall outcome. When the outcomes in question are income gains and losses for two groups of farmers, subjects judge the harm they would not impose through their action to be smaller than the harm they would impose through inaction. Some subjects refuse to reduce cure rates for one group of AIDS patients in order to increase cure rates more for another group, even when group membership was unknowable to anyone, so that, from each patient's point of view, the change would increase the probability of cure. Likewise, they resisted a vaccine that reduced overall mortality in one group but increased deaths from side effects in another group, even when, again, group membership was unknowable. Some people apply a do-no-harm principle to groups without apparent understanding of how such a principle might be justified in terms of its consequences. The capacity for such judgments makes them vulnerable to learning principles that have no justification at all. 相似文献

We report on two studies of anger and aggression in women. One study concerns an experimental study of anger induction in aggressive and non-aggressive sportswomen. It was found that sports choice in itself, contrary to expectation, does not predict anger arousal and aggressive behavior in the laboratory. However, at an individual level the anger proneness of the subject, as measured by a questionnaire we developed, was related to the intensity of aggressive behavior and subjectively reported anger. The second study concerns the activating effects of androgens on aggression and anger proneness. In a group of 22 female-to-male transsexuals, a battery of anger proneness and aggression questionnaires was administered twice: shortly before and 3 months after the start of androgen treatment. Administration of androgens was clearly associated with an increaese in anger proneness, although there were no changes in several aspects of overt aggressive behavior. © 1994 Wiley-Liss, Inc. 相似文献

Parental involvement in their adolescents’ education plays an important role in promoting their children's academic outcomes. Yet, more research is needed to examine the relationship between parenting practices and parental warmth as well as to consider the potential joint contribution of warmth from both fathers and mothers. Thus, the primary purpose of the current study is to examine the extent to which patterns of parental warmth across fathers and mothers moderate the association between parental involvement and adolescents’ grade point average (GPA) and school engagement behaviors. Latent profile analysis was conducted to identify disparate profiles of fathers’ and mothers’ warmth within a nationally representative sample of 2,306 youths (51% male; mean age = 15.31 years, SD = 1.50; 77% non-Hispanic White) residing in opposite-sex, two-parent families from Wave I and II of the National Longitudinal Study of Adolescent to Adult Health. Latent-class enumeration processes support a five-profile solution characterized by differences in levels of parental warmth and congruency across parents: (a) Congruent High Warmth, (b) Congruent Moderate Warmth, (c) Congruent Low Warmth, (d) Incongruent High Mother/Low Father Warmth, and (e) Incongruent Low Father/Lower Mother Warmth. Subsequent multiple linear regression analyses reveal a moderating effect for Congruent Low Warmth on the relationship between parental involvement and adolescents’ GPA. Ultimately, the results show that variation in parental warmth exists across fathers and mothers with differing impact on adolescents’ outcomes. Excluding one parent without considering the joint effects of both parents will not produce an accurate and precise understanding of parenting in research or practice. 相似文献
