Although the ability of autistic adults to recognize others' emotions has been extensively studied, less attention has been given to how they respond to these emotions. We examined two aspects of autistic and non-autistic adults' responsiveness to the emotional expressions of non-autistic actors: their perspectives on the appropriate way of responding to others' emotions and their awareness of others' perceptions of the likely appropriateness of such responses. Autistic (N = 63) and non-autistic (N = 67) adult samples viewed videos of 74 dyadic social interactions displaying different examples of 12 emotions expressed by one actor in response to the behavior of the other.

Difficulties in reading others' minds make it difficult to anticipate their future behaviour. It has often been argued that such difficulties contribute to autistic individuals becoming enmeshed in criminal activity. However, supportive scientific evidence is virtually non-existent.

Emotion recognition difficulties are considered to contribute to social-communicative problems for autistic individuals and awareness of such difficulties may be critical for the identification and pursuit of strategies that will mitigate their adverse effects. We examined metacognitive awareness of face emotion recognition responses in autistic (N = 63) and non-autistic (N = 67) adults across (a) static, dynamic and social face emotion stimuli, (b) free- and forced-report response formats, and (c) four different sets of the six "basic" and six "complex" emotions. Within-individual relationships between recognition accuracy and post-recognition confidence provided no indication that autistic individuals were poorer at discriminating correct from incorrect recognition responses than non-autistic individuals, although both groups exhibited marked inter-individual variability.

Emotion recognition difficulties are considered to contribute to social-communicative problems for autistic individuals. Prior research has been dominated by a focus on forced-choice recognition response accuracy for static face presentations of basic emotions, often involving small samples. Using free-report and multiple-choice response formats, we compared emotion recognition in IQ-matched autistic (N = 63) and nonautistic (N = 67) adult samples using 12 face emotion stimuli presented in three different stimulus formats (static, dynamic, social) that varied the degree of accompanying contextual information.

Early identification of autism, followed by appropriate intervention, has the potential to improve outcomes for autistic individuals. Numerous screening instruments have been developed for children under 3 years of age. Level 1 screeners are used in large-scale screening to detect at-risk children in the general population; Level 2 screeners are concerned with distinguishing children with signs of autism from those with other developmental problems.

Objective: Three studies examined the influence of a witness's identification speed on the identification decision of another witness.

Hypotheses: Based on research documenting cowitness effects we expected cowitness speed to affect identification decisions from target-absent photospreads. Without prior research testing the effects of cowitness speed, we did not have a specific prediction regarding how fast (vs.
