Odor hedonic capacity and anhedonia in schizophrenia and unaffected first-degree relatives of schizophrenia patientsVidyulata Kamath
Neuropsychiatry Section, Department of Psychiatry, University of Pennsylvania School of Medicine, Philadelphia, PA, USA
Schizophr Bull 39:59-67. 2013..We also examine odor valence processing unirhinally, rather than birhinally, to probe possible lateralized differences in patients' hedonic processing deficits...
An odor-specific threshold deficit implicates abnormal cAMP signaling in youths at clinical risk for psychosisVidyulata Kamath
Neuropsychiatry Section, Department of Psychiatry, University of Pennsylvania Perelman School of Medicine, Philadelphia, PA, USA
Schizophr Res 138:280-4. 2012..Odor-detection thresholds to two odorants that differ in the degree to which they activate intracellular cAMP were assessed in clinical risk and low-risk participants...
Effects of the val(158)met catechol-O-methyltransferase gene polymorphism on olfactory processing in schizophreniaVidyulata Kamath
Department of Psychiatry, University of Pennsylvania Perelman School of Medicine, Philadelphia, PA 19104, USA
Behav Neurosci 126:209-15. 2012..Future studies that examine the olfactory processing deficit in schizophrenia with respect to other olfactory measures and COMT haplotypes is warranted...
Identification of pleasant, neutral, and unpleasant odors in schizophreniaVidyulata Kamath
Department of Psychiatry, University of Pennsylvania School of Medicine, Philadelphia, PA, USA
Psychiatry Res 187:30-5. 2011....
Is the odour identification deficit in schizophrenia influenced by odour hedonics?Vidyulata Kamath
Department of Psychology, University of Central Florida, Orlando, USA
Cogn Neuropsychiatry 16:448-60. 2011..CONCLUSIONS. Results provide preliminary support for a specific deficit in identifying pleasant odours in patients with schizophrenia. Future studies separating odours by valence categories are warranted...
Olfactory identification performance in individuals with psychometrically-defined schizotypyVidyulata Kamath
Department of Psychology, University of Central Florida, Orlando, FL 32816, USA
Schizophr Res 100:212-5. 2008..The findings may reflect either the abbreviated nature of the measures used, or a lack of reliable olfactory performance differences in schizotypy...
The relationship between interview-based schizotypal personality dimension scores and the continuous performance testJeffrey S Bedwell
Department of Psychology, University of Central Florida, Orlando, FL 32816 1390, USA
Schizophr Res 108:158-62. 2009..Findings also add to a growing literature suggesting that Interpersonal SPD symptoms are primarily related to omission errors, while Disorganized SPD symptoms are primarily related to false alarm errors...
A meta-analysis of emotion perception and functional outcomes in schizophreniaFarzin Irani
Neuropsychiatry Section, Department of Psychiatry, University of Pennsylvania School of Medicine, Philadelphia, PA 19104, USA
Schizophr Res 137:203-11. 2012..Given its pervasive nature, there is a need to quantitatively examine whether this dysfunction impacts functional outcomes. We used a meta-analytic strategy to combine results from several studies and examine synthesized effect sizes...
Association of schizophrenia with the phenylthiocarbamide taste receptor haplotype on chromosome 7qPaul J Moberg
Neuropsychiatry Section, Schizophrenia Research Center, Department of Psychiatry, University of Pennsylvania Perelman School of Medicine, Philadelphia, PA, USA
Psychiatr Genet 22:286-9. 2012..The PTC nontaster haplotype is a genetic marker that may be used to identify subsets of schizophrenia patients who potentially harbor vulnerability genes in this region of chromosome 7q...
The backward masking red light effect in schizophrenia: relationship to clinical features and neurocognitive performanceJeffrey S Bedwell
Department of Psychology, University of Central Florida, Orlando, FL 32816 1390, USA
J Abnorm Psychol 120:490-6. 2011..In contrast, there was no relationship between the red light change score and any of the neurocognitive variables in the control group...
The influence of semantic processing on odor identification ability in schizophreniaVidyulata Kamath
Neuropsychiatry Section, Department of Psychiatry, University of Pennsylvania Perelman School of Medicine, Philadelphia, PA, USA
Arch Clin Neuropsychol 28:254-61. 2013..No relationship was observed between olfactory and semantic task performance in patients. These data suggest that odor identification deficits may not be primarily due to semantic processing deficits in schizophrenia...
Comparison of three computer-administered cognitive tasks as putative endophenotypes of schizophreniaJeffrey S Bedwell
Department of Psychology, University of Central Florida, Orlando, FL 32816 1390, USA
Schizophr Res 88:36-46. 2006..Based on performance from the community-identified schizotypes, results suggest that performance on the CPT may represent a more robust endophenotype of schizophrenia, compared to the SOA and WCST...
