This study examined the ability of young children with autism spectrum disorders (ASD) to detect affective correspondences between facial and vocal expressions of emotion using an intermodal matching paradigm. Four-year-old children with ASD (n = 18) and their age-matched normally developing peers (n = 18) were presented pairs of videotaped facial…

This experiment was conducted to investigate cross-modal interactions in the emotional experience of music listeners. Previous research showed that visual information present in a musical performance is rich in expressive content, and moderates the subjective emotional experience of a participant listening and/or observing musical stimuli [Vines,…

Schizophrenia may be associated with a fundamental disturbance in the temporal coordination of information processing in the brain, leading to classic symptoms of schizophrenia such as thought disorder and disorganized and contextually inappropriate behavior. Despite the growing interest and centrality of time-dependent conceptualizations of the…

Purpose: To examine the effect of fundamental frequency (F0) on the intelligibility of speech with flattened F0 contours in noise. Method: Participants listened to sentences produced by 2 female talkers in white noise. The listening conditions included the unmodified original sentences and sentences with resynthesized F0 that reflected the average…

An important characteristic of autism spectrum disorder (ASD) is increased visual detail perception. Yet, there is no standing neurobiological explanation for this aspect of the disorder. We show evidence from EEG data, from 31 control subjects (three females) and 13 subjects (two females) aged 16-28 years, for a specific impairment in object…

Previous research has shown that illusions of recognition memory based on enhanced perceptual fluency are sensitive to the perceptual match between the study and test phases of an experiment. The results of the current study strengthen that conclusion, as they show that participants will not interpret enhanced perceptual fluency as a sign of…

Contrary to Albert's claims, the results of previous studies do not favor a perceived contrast model over a ratio-of-perceived-contrasts model (see Points 1-3 below and our main response). Realizing that a simple perceived contrast model leads to predictions that violate "common sense," Albert postulated a division of the continuous dimension of…

This study examined the selective attention abilities of a simple, artificial, evolved agent and considered implications of the agent's performance for theories of selective attention and action. The agent processed two targets in continuous time, catching one and then the other. This task required many cognitive operations, including prioritizing…

Models of compensation for phonological variation in spoken word recognition differ in their ability to accommodate complete assimilatory alternations (such as run assimilating fully to rum in the context of a quick run picks you up). Two experiments addressed whether such complete changes can be observed in casual speech, and if so, whether they…

This paper examines the relationship between altruism and positive illusion, as formulated by Taylor and Brown (1988). It was predicted that, compared to the non-exemplary, general population, exemplary altruists would exhibit a higher level of positive illusion, which, in turn, suggests a higher level of mental health. Forty exemplary altruists…

In a recent paper, Johnson, Bouchard, Krueger, McGue, and Gottesman (2004) addressed a long-standing debate in psychology by demonstrating that the g factors derived from three test batteries administered to a single group of individuals were completely correlated. This finding provided evidence for the existence of a unitary higher-level general…

Research on visual perception in Autism Spectrum Disorder (ASD) tries to reveal the underlying mechanisms of aberrant local and global processing. Global motion perception is one way to study this aspect of ASD. We used plaid motion stimuli, which can be perceived as a coherently moving pattern, requiring feature integration, or as two transparent…

The present study examined the perception of Mandarin disyllabic tones by inexperienced American English speakers. Participants heard two naturally-produced Mandarin disyllables, and indicated if the two were the same or different. A small native Mandarin-speaking control group participated as well. All 21 possible Mandarin contrasts where the…

The purpose of this study was to assess teacher perceptions regarding the effectiveness of online courses as a delivery method for professional development. Participants were divided into two groups, educators who have participated in and now teach professional development courses online (instructors) and educators who have participated in the…

On the basis of the connectionist model of leadership, we examined perceptions of leadership as a function of the contextual factors of race (Asian American, Caucasian American) and occupation (engineering, sales) in 3 experiments (1 student sample and 2 industry samples). Race and occupation exhibited differential effects for within- and…
