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

Much coping research has been conducted comparing members of different ethnic groups using discrete racial classifications. However, the past two decades have seen the construct of ethnicity evolve into a complex variable that must be assessed in a more comprehensive way. This study explored how ethnicity, a discrete variable, and the continuous variables of a person's ethnic identity and self-construal contribute to the use of particular coping strategies across various situations. One hundred twelve seventh graders (67 African Americans and 45 Caucasian Americans) from three suburban middle schools completed questionnaires assessing ethnic identity, self-construal, and coping strategies for medical, test, and social criticism stressors. Results supported the hypothesis that ethnicity as a discrete variable is not associated with coping, but that ethnic identity and self-construal are. It was also found that high scores on the ethnic identity and self-construal scales were indicative of more positive psychological adjustment. Implications for future research and methodological considerations are discussed. 相似文献

Relationships among science, public policy, and the media have long been a topic of controversy. A discussion of this controversy serves to place views on the Rind et al. affair in a broader context and set the stage for constructing more effective working relationships between scientists and both policy and media experts. To advance these relationships, the author offers several recommendations that emphasize ongoing institutional activities and encourage collaboration with other professional organizations. 相似文献

Pigeons were trained on a multiple schedule in which separate concurrent schedules were presented in the two components of the schedule. During one component, concurrent variable-interval 40-sec variable-interval 80-sec schedules operated. In the second component, concurrent variable-interval 40-sec variable-interval 20-sec schedules operated. After stable baseline performance was obtained in both components, extinction probe choice tests were presented to assess preference between the variable-interval 40-sec schedules from the two components. The variable-interval 40-sec schedule paired with the variable-interval 80-sec schedule was preferred over the variable-interval 40-sec schedule paired with the variable-interval 20-sec schedule. The subjects were also exposed to several resistance-to-change manipulations: (1) prefeeding prior to the experimental session, (2) a free-food schedule added to timeout periods separating components, and (3) extinction. The results indicated that preference and resistance to change do not necessarily covary. 相似文献

Auditory saltation is a misperception of the spatial location of repetitive, transient stimuli. It arises when clicks at one location are followed in perfect temporal cadence by identical clicks at a second location. This report describes two psychophysical experiments designed to examine the sensitivity of auditory saltation to different stimulus cues for auditory spatial perception. Experiment 1 was a dichotic study in which six different six-click train stimuli were used to generate the saltation effect. Clicks lateralised by using interaural time differences and clicks lateralised by using interaural level differences produced equivalent saltation effects, confirming an earlier finding. Switching the stimulus cue from an interaural time difference to an interaural level difference (or the reverse) in mid train was inconsequential to the saltation illusion. Experiment 2 was a free-field study in which subjects rated the illusory motion generated by clicks emitted from two sound sources symmetrically disposed around the interaural axis, ie on the same cone of confusion in the auditory hemifield opposite one ear. Stimuli in such positions produce spatial location judgments that are based more heavily on monaural spectral information than on binaural computations. The free-field stimuli produced robust saltation. The data from both experiments are consistent with the view that auditory saltation can emerge from spatial processing, irrespective of the stimulus cue information used to determine click laterality or location. 相似文献

Superconditioning is said to occur when learning an association between a conditioned stimulus (CS) and unconditioned stimulus (US) is facilitated by pairing the CS with the US in the presence of a previously established conditioned inhibitor. Previous demonstrations of superconditioning have been criticized because their control conditions have allowed alternative interpretations. Using a within–subjects autoshaping procedure, the present study unambiguously demonstrated superconditioning. The results support the view that superconditioning is the symmetric opposite of blocking. 相似文献

Changes in executive functions have been found in older adults and also in young adults experiencing positive or negative mood states. The current study investigated the hypothesis that older adults would show greater executive function impairment following mood induction than young adults. Ninety-six participants (half aged 19-37, half aged 53-80) completed a neutral, positive, or negative mood induction procedure, followed by the Tower of London planning task. Significant interactions were found between age and mood such that older adults showed greater planning impairment than young adults in both the positive and negative mood conditions. Emotionally salient events occurring before testing may interfere with executive function in older adults. 相似文献
