In order to more fully understand how individual differences influence adaptation to violence, this study examined the moderating influence of resting heart rate (HR) and HR variability (HRV) between community violence (CV) exposure and child reactive/proactive aggression. Forty 7-13-year-old community children self-reported CV exposure (i.e.,…

Inspection Time (IT) is a psychophysical speed measure that has been linked to a range of cognitive abilities with results finding that shorter IT is associated with superior performance in cognitive abilities. Following a recent suggestion by Nettelbeck and Wilson [Nettelbeck, T., & Wilson, C. (2004). The Flynn effect: Smarter not faster.…

It has been suggested that spindle neurons, an evolutionarily unique type of neuron, might be involved in higher-order social, emotional, and cognitive functions. As such, it was hypothesized that these neurons may be particularly important to the pathophysiology of autism, a disease characterized in part by disruption of higher-order social and…

The purpose of the present study was to identify the characteristics of music used to accompany physical exercise and investigate the effects of such music using a qualitative approach. This work underpins the further development of a theoretical structure that is still relatively new. Semi-structured interviews were conducted with a sample of…

Faced with highly complex and ambiguous visual input, human observers must rely on prior knowledge and assumptions to efficiently determine the structure of their surroundings. One of these assumptions is the "light-from-above" prior. In the absence of explicit light-source information, the visual system assumes that the light-source is roughly…

Auditory stream segregation (or streaming) is a phenomenon in which 2 or more repeating sounds differing in at least 1 acoustic attribute are perceived as 2 or more separate sound sources (i.e., streams). This article selectively reviews psychophysical and computational studies of streaming and comprehensively reviews more recent…

It is proposed that the doctrine of autonomic reciprocity be subsumed by a notion of autonomic space, with elements that include principles of autonomic organization and control consistent with a two-dimensional autonomic space. A quantitative model is derived that describes translation of the model into a functional output surface. (SLD)

Theories of agency--the feeling of being in control of one's actions and their effects--emphasize either perceptual or cognitive aspects. This study addresses both aspects simultaneously in a finger-tapping paradigm. The tasks required participants to detect when synchronization of their taps with computer-controlled tones changed to…

To better understand the origins of autonomic reactivity during marital interactions, this study examined the psychophysiological profiles of prototypically secure (vs. insecure) and deactivating (vs. hyperactivating) adults while they talked about areas of disagreement with their (pre)marital partners. Adults who idealized their caregivers…

Objective: Antisocial behavior frequently occurs in families. This study investigated whether autonomic hypoarousal and hyporesponsivity, which have been observed in antisocial individuals of all ages, are passed from fathers to male offspring. Method: The study included 44 boys with early-onset conduct disorder and 36 healthy controls (8 to 13…

This meta-analysis of 58 resting baseline studies, 25 startle studies, 17 standardized trauma cue studies, and 22 idiographic trauma cue studies compared adults with and without posttraumatic stress disorder (PTSD) on psychophysiological variables: facial electromyography (EMG), heart rate (HR), skin conductance (SC), and blood pressure.…

A review of Psychophysiology of Learning and Memory (Thomas, Springfield, Illinois, 1971) by Elio Maggio. (DB)

The authors forward the hypothesis that social exclusion is experienced as painful because reactions to rejection are mediated by aspects of the physical pain system. The authors begin by presenting the theory that overlap between social and physical pain was an evolutionary development to aid social animals in responding to threats to inclusion.…

Mental preparation aids performance and induces multiple physiological changes that should inform concepts of preparation. To date, however, these changes have been interpreted as being due to a global preparatory process (e.g., attention or alertness). The authors review psychophysiological and performance investigations of preparation. Concepts…

Attempts to explain the experience of somatic complaints among children and adolescents suggest that they may in part result from the influence of particular strategies for coping with anger on the longevity of negative emotions. To explore these relationships British (n = 393) and Dutch (n = 99) children completed a modified version of the…
