Five studies were conducted to develop a measure of employee impression management behaviors based on the taxonomy proposed by Jones and Pittman. In Study 1, 44 items were given to student judges to verify the content validity of the items. In Study 2, the scale was administered to a sample of professionals and exploratory factor analysis was conducted. Based on the results, revisions to the sc...

Firemaster® 550 (FM 550), a fire-retardant mixture used in foam-based products, was recently identified as a common contaminant in household dust. The chemical structures of its principle components suggest they have endocrine disrupting activity, but nothing is known about their physiological effects at environmentally relevant exposure levels. The goal of this exploratory study was to evaluat...

Young songbirds produce vocal "babbling," and the variability of their songs is thought to underlie a process of trial-and-error vocal learning. It is known that this exploratory variability requires the "cortical" component of a basal ganglia (BG) thalamocortical loop, but less understood is the role of the BG and thalamic components in this behavior. We found that large bilateral lesions to t...

Research on exploratory and searching behavior of animals and robots has attracted an increasing amount of interest recently. Existing works have focused mostly on exploratory behavior guided by vision and audition. On the other hand, research on smell-guided exploration has been lacking, even though animals may use the sense of smell more widely than sight or hearing to search for food and to ...

We investigated the influence of four different behavioral states on tactile responses recorded simultaneously via arrays of microwires chronically implanted in the vibrissal representations of the rat ventral posterior medial nucleus (VPM) of the thalamus and the primary somatosensory cortex (SI). Brief (100 microsecond) electrical stimuli delivered via a cuff electrode to the infraorbital ner...

objective: the purpose of this study is to provide evidence of validity of the relational and overt aggression questionnaire (roaq) among iranian elementary students. methods: three hundred and forty nine 4th and 5th grade students (ages 9 and 10) participated in this study. participants completed the roaq. the scale consisted of 33 items designed to measure self-report aggressive behaviors for...

In contrast to the long-held assumption that the organization of behavior is best characterized as the perception of a sensory stimulus followed by appropriate response (i.e., “sensorimotor hypothesis”), recent converging evidence from multiple systems and fields of study instead suggests that both ancestral and extant general brain function is best described in operant terms. Rather than speci...

BACKGROUND One much needed tool to assist with the monitoring and evaluation of Human Immunodeficiency Virus (HIV) prevention programs is to provide a valid instrument to measure protective sexual behavior and related factors. OBJECTIVES The current study aimed to design a valid and reliable instrument to predict the protective sexual behaviors of women at risk of HIV in Iran. PATIENTS AND ...

Our previous studies found that serotonin transporter (SERT) knock-out mice showed increased sensitivity to minor stress and increased anxiety-like behavior but reduced locomotor activity. These mice also showed decreased density of 5-hydroxytryptamine (5-HT1A) receptors in the hypothalamus, amygdala, and dorsal raphe. To evaluate the contribution of hypothalamic 5-HT1A receptors to these pheno...

CASK-interacting nucleosome assembly protein (CINAP) has been shown to interact with the calcium/calmodulin-dependent serine kinase (CASK) and the T-box transcription factor T-brain-1 (Tbr1) thus modulating the expression of N-methyl-D-aspartic acid receptor subunit 2b (NMDAR2b) in cultured hippocampal neurons. To explore the physiological significance of CINAP in vivo, CINAP knockout mice were...
