Development Of The Anxiety Change Expectancy Scale (Aces) And Validation In College, Community, And Clinical Samples., David J A Dozois, Henny A Westra

Psychology Publications

This study investigated the psychometric properties of a newly developed 20-item instrument that assesses one's anticipation of being able to change anxiety: the Anxiety Change Expectancy Scale (ACES). Study 1 evaluated the ACES in undergraduate university students, self-identified as experiencing difficulties with anxiety. Study 2 examined the ACES in a community sample of persons with anxiety difficulties. Study 3 tested the utility of the ACES in predicting treatment change in a group of individuals with generalized anxiety disorder participating in group cognitive behavioral therapy for anxiety. Across these samples, the ACES demonstrated excellent internal reliability (coefficient alphas=.89-.92) as well as …

The anterior medial prefrontal (AMPFC) and retrosplenial (RSC) cortices are active during self-referential decision-making tasks such as when participants appraise traits and abilities, or current affect. Other appraisal tasks requiring an evaluative decision or mental representation, such as theory of mind and perspective-taking tasks, also involve these regions. In many instances, these types of decisions involve a subjective opinion or preference, but also a degree of ambiguity in the decision, rather than a strictly veridical response. However, this ambiguity is generally not controlled for in studies that examine self-referential decision-making. In this functional magnetic resonance imaging experiment with 17 healthy …

Glutamate Receptors In Perirhinal Cortex Mediate Encoding, Retrieval, And Consolidation Of Object Recognition Memory., Boyer D Winters, Timothy J Bussey Apr 2005

Glutamate Receptors In Perirhinal Cortex Mediate Encoding, Retrieval, And Consolidation Of Object Recognition Memory., Boyer D Winters, Timothy J Bussey

Brain and Mind Institute Researchers' Publications

Object recognition is consistently impaired in human amnesia and animal models thereof. Results from subjects with permanent brain damage have revealed the importance of the perirhinal cortex to object recognition memory. Here, we report evidence from rats for interdependent but distinct stages in object recognition memory (encoding, retrieval, and consolidation), which require glutamate receptor activity within perirhinal cortex. Transient blockade of AMPA receptor-mediated synaptic transmission within perirhinal cortex disrupted encoding for short- and long-term memory as well as retrieval and consolidation. In contrast, transient NMDA receptor blockade during encoding affected only long-term object recognition memory; NMDA receptor activity was also …

A Contralateral Preference In The Lateral Occipital Area: Sensory And Attentional Mechanisms., Matthias Niemeier, Herbert C Goltz, Anil Kuchinad, Douglas B Tweed, Tutis Vilis Mar 2005

A Contralateral Preference In The Lateral Occipital Area: Sensory And Attentional Mechanisms., Matthias Niemeier, Herbert C Goltz, Anil Kuchinad, Douglas B Tweed, Tutis Vilis

Here we examined the level of the lateral occipital (LO) area within the processing stream of the ventral visual cortex. An important determinant of an area's level of processing is whether it codes visual elements on both sides of the visual field, as do higher visual areas, or prefers those in the contralateral visual field, as do early visual areas. The former would suggest that LO, on one side, combines bilateral visual elements into a whole, while the latter suggests that it codes only the parts of forms. We showed that LO has a relative preference for visual objects in …

Transient Inactivation Of Perirhinal Cortex Disrupts Encoding, Retrieval, And Consolidation Of Object Recognition Memory., Boyer D Winters, Timothy J Bussey Jan 2005

Transient Inactivation Of Perirhinal Cortex Disrupts Encoding, Retrieval, And Consolidation Of Object Recognition Memory., Boyer D Winters, Timothy J Bussey

Brain and Mind Institute Researchers' Publications

Damage to perirhinal cortex (PRh) impairs object recognition memory in humans, monkeys, and rats when tested in tasks such as delayed nonmatching to sample, visual paired comparison, and its rodent analog, the spontaneous object recognition task. In the present study, we have capitalized on the discrete one-trial nature of the spontaneous object recognition task to investigate the role of PRh in several distinct stages of object recognition memory. In a series of experiments, transient inactivation of PRh was accomplished with bilateral infusions of lidocaine directly into PRh immediately before the sample phase (encoding), immediately before the choice phase (retrieval), or …

Intelligence Correlates Of Transcendent Beliefs: A Preliminary Study, Nicole Lukey, Imants Barušs Jan 2005

Intelligence Correlates Of Transcendent Beliefs: A Preliminary Study, Nicole Lukey, Imants Barušs

Psychology

In previous research, Barušs and Moore had identified a material-transcendent dimension of beliefs about consciousness and reality that underlies the Western intellectual tradition including the academic study of consciousness. At one pole, materialists believe that reality is entirely physical in nature, whereas those tending toward the transcendent pole believe that reality cannot exhaustively be captured in physical terms. More recently, Jewkes and Barušs had found a number of personality correlates of transcendent beliefs including a tendency toward curiosity and a rational approach to the world [1]. These previous results prompted the present study in which 39 undergraduate psychology students at …

The Validity Of The Brief Version Of The Fear Of Negative Evaluation Scale., Kerry A Collins, Henny A Westra, David J A Dozois, Sherry H Stewart Jan 2005

The Validity Of The Brief Version Of The Fear Of Negative Evaluation Scale., Kerry A Collins, Henny A Westra, David J A Dozois, Sherry H Stewart

Psychology Publications

The Fear of Negative Evaluation Scale [FNE; J. Consult. Clin. Psychol. 33 (1969) 448] is a commonly used measure of social anxiety. A brief version of the scale (FNEB) is available for convenient administration. Despite being widely advocated for use, the psychometric properties of the FNEB have not been evaluated with clinically anxious samples. The present study addressed the reliability and validity of the FNEB in a clinical sample of individuals with either social phobia (n = 82) or panic disorder (n = 99) presenting for treatment. Factor analysis supported the construct validity of the FNEB. The validity of the …
