Substance use may influence mothers’ responsiveness to their infants and negatively impact the parent–infant relationship. Maternal substance use may co-opt neural circuitry involved in caregiving, thus reducing the salience of infant cues and diminishing the sense of reward experienced by caring for infants. Gaps in understanding exist with regard to the mechanisms by which substance use operates to influence mothers’ processing of infant cues and how this translates to caregiving. Therefore, we examined how substance use might relate to maternal neural responses to infant cues using event-related potentials (ERPs). Substance-using (n = 29) and nonsubstance-using (n = 29) mothers viewed photographs of infant faces and heard recordings of infant vocalizations while electroencephalography was recorded simultaneously. Three specific ERP components were used to examine initial processing of infant faces (N170) and cries (N100), and attentional allocation to infant faces and cries (P300). Substance-using mothers did not discriminate facial affect at early encoding stages (N170), were generally slower to orient to infant cries (N100), showed heightened responses to neutral faces (P300), and failed to adaptively differentiate between high-distress versus low-distress cries (P300). These differences may be important to caregiving behaviors associated with the formation of mother–child attachment. Implications are discussed, as are limitations and future directions. 相似文献

It is often assumed that perceptual experience provides evidence about the external world. But much perception can occur unconsciously, as in cases of masked priming or blindsight. Does unconscious perception provide evidence as well? Many theorists maintain that it cannot, holding that perceptual experience provides evidence in virtue of its conscious character. Against such views, I challenge here both the necessity and, perhaps more controversially, the sufficiency of consciousness for perception to provide evidence about the external world. In addition to motivating and defending the idea that unconscious perception can and does often provide evidence, I observe that whether or not perceptual phenomenology is relevant to the evidentiary status of perception depends on the nature of consciousness. And I argue that a well‐supported theory of consciousness—higher‐order thought theory—invites a striking conclusion: that perceptual phenomenology is not on its own sufficient to provide for evidence of the external world. 相似文献

This paper introduces a theoretical framework for research on the dynamics of self- and other-focused emotional intelligence (EI). The EI-framework focuses specifically on the interplay between different EI dimensions when individuals are processing their own emotions and the emotions of others. The framework captures different phases of processing self- and other-emotions. The first phase consists of situational cues (e.g., an argument) that elicit interdependent emotions in the self and others. The next phase specifies differential and interacting effects of EI dimensions when processing these emotions, and the third phase describes what proximal and distal consequences this processing may have. In addition, the framework includes candidate dispositional and contextual factors (e.g., emotion type, motivation) that may qualify the process. 相似文献

Stochastic dominance concerns conditions on outcome probabilities that are necessary and sufficient for one act to be (strictly) preferred to another according to all preference relations that share certain properties, one of which customarily is an Archimedean property sufficient to entail existence of real-valued representations. We relax this assumption to permit linear lexicographic utility of finite and known dimensionality. In some situations, levels of the lexicographic hierarchy could correspond to explicit criteria or attributes. In our model, subjective probabilities emerge as matrix premultipliers of the outcome utility vectors. We thus obtain matrix probability generalizations of the familiar cumulative probability conditions for stochastic dominance. 相似文献

In an attempt to increase the reliability of the demonstrator-consistent responding effect produced in the bidirectional
control procedure, experiments 1–4 sought conditions that would magnify the matching effect. The aim was to produce a robust
demonstrator-consistent responding effect in order that future analytic experiments could investigate the psychological processes
responsible for this effect. The joystick responses of observer rats trained using the standard bidirectional control procedure
parameters were compared with those of observers subject to conditions identified in the social learning literature as favourable
for imitation. Unlike mice, observer rats in experiments 1 a and 1 b tended to push a joystick in the same direction as their
demonstrators when the demonstrators were either familiar or unfamiliar males and females. Comparable demonstrator-consistent
responding occurred following observation of a standard and a salient joystick response (experiment 2). Experiment 3 showed
that the discriminative accuracy of a demonstrator’s responding was important for matching behaviour, and suggested that matching
might be enhanced with more than the conventional single observation session. Experiment 4 confirmed that the bidirectional
control effect is sensitive to the amount of observational experience; after six observation sessions, demonstrator-inconsistent
responding occurs. The results of experiments 1–3 are, and those of experiment 4 are not, compatible with the hypothesis that
demonstrator-consistent responding in the bidirectional control is caused by olfactory cues deposited by demonstrators on
the joystick.

In a water‐licking experiment with rats, the effects of the extinction of a first‐order conditioned stimulus (CS1) on the suppression of licking established for a second‐order conditioned stimulus (CS2) were explored. Extinction of the first‐order conditioned response (CR1) attenuated the conditioned suppression induced by CS2 when the rats had been allowed to lick water during the CR1 extinction phase. However, if water had been unavailable during the CR1 extinction phase, suppression by CS2 was not affected. The latter result is consistent with other studies of rats' conditioned suppression and suggests that the underlying mechanism of second‐order conditioning in this experiment is a connection between CS2 and the response elicited by CS1 rather than a CS2‐CS1 connection. The former result was interpreted as the CR1 extinction phase encouraging the rats to lick water despite the fear elicited by CS1, and thus, in testing, they licked despite the fear elicited by CS2. 相似文献

This study investigated the effects of written text and pictorial cuing with supplemental video feedback on the social communication of 5 students with autism and social deficits. Two peers without disabilities participated as social partners with each child with autism to form five triads. Treatment was implemented twice per week and consisted of 10 min of systematic instruction using visual stimuli, 10 min of social interaction, and 10 min of self‐evaluation using video feedback. Results showed increases in targeted social communication skills when the treatment was implemented. Some generalized treatment effects were observed across untrained social behaviors, and 1 participant generalized improvements within the classroom. In addition, naive judges reported perceived improvements in the quality of reciprocal interactions. These findings support recommendations for using visually cued instruction to guide the social language development of young children with autism as they interact with peers without disabilities. 相似文献
