Action adaptation during natural unfolding social scenes influences action recognition and inferences made about actor beliefs (2016)
Journal Article
Keefe, B. D., Wincenciak, J., Jellema, T., Ward, J. W., & Barraclough, N. E. (2016). Action adaptation during natural unfolding social scenes influences action recognition and inferences made about actor beliefs. Journal of Vision, 16(9), 1-20. https://doi.org/10.1167/16.9.9

When observing another individual's actions, we can both recognize their actions and infer their beliefs concerning the physical and social environment. The extent to which visual adaptation influences action recognition and conceptually later stages... Read More

Emotional actions are coded via two mechanisms : with and without identity representation (2016)
Journal Article
Wincenciak, J., Ingham, J., Jellema, T., & Barraclough, N. E. (2016). Emotional actions are coded via two mechanisms : with and without identity representation. Frontiers in Psychology, 7, 693-1-693-13. doi:10.3389/fpsyg.2016.00693

Accurate perception of an individual’s identity and emotion derived from their actions and behavior is essential for successful social functioning. Here we determined the role of identity in the representation of emotional whole-body actions using vi... Read More

Atypical emotional anticipation in high-functioning autism (2015)
Journal Article
Jellema, T., Burnett, H. G., & Palumbo, L. (2015). Atypical emotional anticipation in high-functioning autism. Molecular Autism, 6(1), 47-1-47-17. https://doi.org/10.1186/s13229-015-0039-7

Background Understanding and anticipating others’ mental or emotional states relies on the processing of social cues, such as dynamic facial expressions. Individuals with high-functioning autism (HFA) may process these cues differently from individua... Read More

Impaired identification of impoverished animate but not inanimate objects in adults with high-functioning autism spectrum disorder (2014)
Journal Article
Burnett, H. G., Panis, S., Wagemans, J., & Jellema, T. (2015). Impaired identification of impoverished animate but not inanimate objects in adults with high-functioning autism spectrum disorder. Autism Research, 8(1), 52-60. https://doi.org/10.1002/aur.1412

The ability to identify animate and inanimate objects from impoverished images was investigated in adults with high-functioning autism spectrum disorder (HFA) and in matched typically developed (TD) adults, using a newly developed task. Consecutive f... Read More

Involuntary social cue integration in patients with obsessive compulsive disorder (2013)
Journal Article
Tumkaya, S., Karadag, F., Jellema, T., Oguzhanoglu, N. K., Ozdel, O., Atesci, F. C., & Varma, G. (2014). Involuntary social cue integration in patients with obsessive compulsive disorder. Comprehensive Psychiatry, 55(1), 137-144. https://doi.org/10.1016/j.comppsych.2013.08.007

Objective Patients with obsessive compulsive disorder (OCD) have inferior social functioning compared to healthy controls, but the exact nature of these social deficits, and the underpinning mechanisms, are unknown. We sought to investigate social fu... Read More

Implicit social learning in relation to autistic-like traits (2012)
Journal Article
Hudson, M., Nijboer, T. C. W., & Jellema, T. (2012). Implicit social learning in relation to autistic-like traits. Journal of Autism and Developmental Disorders, 42(12), (2534-2545). doi:10.1007/s10803-012-1510-3. ISSN 0162-3257

We investigated if variation in autistic traits inthe typically-developed population (using the AutismspectrumQuotient, AQ) influenced implicit learning ofsocial information. In the learning phase, participantsrepeatedly observed two identities whose... Read More

Resolving ambiguous behavioral intentions by means of involuntary prioritization of gaze processing (2011)
Journal Article
Jellema, T., & Hudson, M. (2011). Resolving ambiguous behavioral intentions by means of involuntary prioritization of gaze processing. Emotion, 11(3), (681-686). doi:10.1037/a0023264. ISSN 1528-3542

Anticipation of others' actions is of paramount importance in social interactions. Cues such as gaze direction and facial expressions can be informative, but can also produce ambiguity with respect to others' intentions. We investigated the combined... Read More

Anticipation of action intentions in autism spectrum disorder (2011)
Journal Article
Hudson, M., Burnett, H. G., & Jellema, T. (2012). Anticipation of action intentions in autism spectrum disorder. Journal of Autism and Developmental Disorders, 42(8), 1684-1693. doi:10.1007/s10803-011-1410-y

We investigated whether individuals with a mild form of autism spectrum disorder (ASD) are influenced by an actor’s gaze direction when anticipating how an observed action will continue in the immediate future. Participants observed a head rota... Read More

Unequal impairment in the recognition of positive and negative emotions after right hemisphere lesions: A left hemisphere bias for happy faces (2011)
Journal Article
Nijboer, T. C. W., & Jellema, T. (2012). Unequal impairment in the recognition of positive and negative emotions after right hemisphere lesions: A left hemisphere bias for happy faces. Journal of neuropsychology, 6(1), 79-93. doi:10.1111/j.1748-6653.2011.02007.x

The processing of several important aspects of a human face was investigated in a single patient (LZ), who had a large infarct of the right hemisphere involving the parietal, and temporal lobes with extensions into the frontal region. LZ showed selec... Read More

Biases in the perception and affective valence of neutral facial expressions induced by the immediate perceptual history (2011)
Journal Article
Pecchinenda, A., Palumbo, L., Tan, E. G., & Jellema, T. (2011). Biases in the perception and affective valence of neutral facial expressions induced by the immediate perceptual history. Visual Cognition, 19(5), (616-634). doi:10.1080/13506285.2011.569775. ISSN 1350-6285

We report a new perceptual distortion of neutral facial expressions induced by the immediate dynamic perceptual history. In Experiment 1, participants evaluated the facial expression on the last frame of videoclips showing morphs from a happy or angr... Read More
