This article explores the cognitive underpinnings of interpersonal closeness in the theoretical context of "including other in the self" and, specifically, the notion of overlap between cognitive representations of self and close others. In each of three studies, participants first rated different traits for self, close others (e.g., romantic partner, best friend), and less close others (e.g., media personalities), followed by a surprise source recognition task (who was each trait rated for?). As predicted, in each study, there were more source confusions between traits rated for self and close others (e.g., a trait rated for self recalled as having been rated for the close other) than between self (or close others) and non-close others. Furthermore, several results suggest that the greater confusions between self and close others are due specifically to interpersonal closeness and not to greater familiarity or similarity with close others 相似文献

In a survey of students from junior high through the undergraduate college level, males consistently out-performed females on a test covering map skills and physical, human, and regional aspects of geography. The gender gap was consistent across all four subfields. It widened with increased education and was significant even after accounting for numerous personal information items that might have explained the difference. This consistent performance difference involving the broad spectrum of geographic knowledge argues against explaining the gender gap as symptomatic of differences in a single underlying factor such as map skills or spatial abilities. Knowledge-based and nonknowledge-based explanations for the gender difference are discussed. 相似文献

It has been documented that some tests ofbackground knowledge underpredict the performance offemale students in college. This study explored whetherthe underprediction phenomenon would also be found for a test that tapped four subfields ofgeography. Students (primarily White, N = 315) enrolledin nine geography classes at a comprehensive, midwesternuniversity completed the Knowledge of Geography (KOG) test during the first week of the semester andconsented to release their first exam grades, finalgrades, and ACT scores. Replicating a previous study(Henrie, Aron, Nelson, & Poole, 1997), there were gender differences favoring males across allfour subfields of the KOG test. KOG test scorescorrelated with grades, but males and females achievedcomparable course grades despite the lower performance of females on the KOG test. Examples illustratehow small differences between predicted and actualgrades can translate into large gender discrepancieswhenever minimum scores from tests that underpredict the performance of a subgroup are used toqualify students for educationalopportunities. 相似文献

ABSTRACT— Love is a perennial topic of fascination for scholars and laypersons alike. Whereas psychological science was slow to develop active interest in love, the past few decades have seen considerable growth in research on the subject, to the point where a uniquely psychological perspective on love can be identified. This article describes some of the more central and well-established findings from psychologically informed research on love and its influence in adult human relationships. We discuss research on how love is defined, the significance of love for human activity and well-being, and evidence about the mechanisms by which love is believed to operate. We conclude by describing several key questions and potentially important new directions for the next wave of psychological science. 相似文献

Although research on the neurobiological foundation of social affiliation has implicated the neuropeptide oxytocin in processes of maternal bonding in mammals, there is little evidence to support such links in humans. Plasma oxytocin and cortisol of 62 pregnant women were sampled during the first trimester, last trimester, and first postpartum month. Oxytocin was assayed using enzyme immunoassay, and free cortisol was calculated. After the infants were born, their interactions with their mothers were observed, and the mothers were interviewed regarding their infant-related thoughts and behaviors. Oxytocin was stable across time, and oxytocin levels at early pregnancy and the postpartum period were related to a clearly defined set of maternal bonding behaviors, including gaze, vocalizations, positive affect, and affectionate touch; to attachment-related thoughts; and to frequent checking of the infant. Across pregnancy and the postpartum period, oxytocin may play a role in the emergence of behaviors and mental representations typical of bonding in the human mother. 相似文献

Memory deficits produced by marijuana arise partly via interaction of the psychoactive component, Delta(9)-tetrahydrocannabinol (Delta(9)-THC), with cannabinoid receptors in the hippocampus. Although cannabinoids acutely reduce glutamate release and block hippocampal long-term potentiation (LTP), a potential substrate for learning and memory, the consequences of prolonged exposure to Delta(9)-THC for hippocampal function are poorly understood. Rats were injected with Delta(9)-THC (10 mg/kg, i.p., q.d.) for 1, 3, or 7 d, and electrophysiological recordings were performed in hippocampal slices 1d after the final injection. At this time, Delta(9)-THC was undetectable in hippocampus using liquid chromatography-mass spectrometry (LC-MS). Hippocampal LTP generated using high-frequency (HFS) or theta burst stimulation was not observed in brain slices from the 7-d Delta(9)-THC-treated animals. Delta(9)-THC also blocked HFS-LTP after 3 d, but not 1 d of treatment. The complete blockade of LTP persisted for 3 d after the last Delta(9)-THC injection, and full reversal of the LTP deficit was not observed up to 14 d following Delta(9)-THC withdrawal. The cannabinoid antagonist AM251 (2 mg/kg), administered before each Delta(9)-THC injection prevented the blockade of LTP, and 7-d treatment with AM251 alone significantly increased the level of LTP. Chronic Delta(9)-THC also produced tolerance to the inhibition of synaptic GABA, but not glutamate release by the agonist WIN55,212-2. These data define consequences of repeated Delta(9)-THC exposure for synaptic plasticity in the hippocampus that may help explain memory impairments in humans following chronic marijuana use. 相似文献
