in order to estimate the relationship between forage quality and preference value of plant species for raini goats(capra aegagrus hircus), a field study was carried out on raini goats’ grazing behavior in some desert habitats.crude protein (as the most important factor affecting forage quality) of all plant species was measured at twophenological stages (spring and summer, 2010) in the dry rang...

preference in human primary visual cortex (V1). Each line corresponds to a different voxel (a 2 2 2 mm cube of cortex) in V1; signals from each voxel were measured using functional magnetic resonance imaging. Orientation preference was measured by showing human observers stimuli like the oriented grating shown in the background. The location of each line represents the location in the visual fi...

There is evidence of a preference for visual symmetry. This is true from mate selection in the animal world to the aesthetic appreciation of works of art. It has been proposed that this preference is due to processing fluency, which engenders positive affect. But is visual symmetry pleasant? Evidence is mixed as explicit preferences show that this is the case. In contrast, implicit measures sho...

Looming objects produce ecologically important signals that can be perceived in both the visual and auditory domains. Using a preferential looking technique with looming and receding visual and auditory stimuli, we examined the multisensory integration of looming stimuli by rhesus monkeys. We found a strong attentional preference for coincident visual and auditory looming but no analogous prefe...

This study investigated whether monkeys recognize when a human experimenter imitates their actions towards an object. Two experimenters faced 10 pigtailed macaques, who were given access to an interesting object. One experimenter imitated the monkeys' object-directed actions, the other performed temporally contingent but structurally different object-directed actions. Results show a significant...

This study examined the effect of attention on 3- to 6-month-olds responses to briefly exposed visual stimuli. In Study I, stimuli presented at 2.5 or 5.0 s resulted in a familiarity preference in a subsequent paired-comparison procedure. A novelty preference was found with 10.0- or 20.0-s exposure durations. In Study 2, a Sesame Street movie elicited heart-rate-defined attention phases and sti...

The ability to identify conspecifics from the face is of primary interest for human social behavior. Newborns' visual preference for schematic face-like stimuli has been recently related to a sensitivity for visual patterns with a greater number of elements in the upper compared to the lower part. At the adult level, neuroimaging studies have identified a network of cortical areas devoted to th...

The effects of menstrual cycle phase and hormones on women's visual ability to detect symmetry and visual preference for symmetry were examined. Participants completed tests of symmetry detection and preference for male facial symmetry at two of three menstrual cycle phases (menses, periovulatory, and luteal). Women were better at detecting facial symmetry during the menses than luteal phase of...

Objectives: 1) To obtain preference scores from patients with breast cancer in Singapore for different stages of breast cancer and hormonal therapy–related adverse effects, and 2) to determine the association of patients’ demographic and clinical characteristics with those preference scores. Methods: A total of 22 health states were used to elicit preference values from 64 patients with breast ...

To what extent can simple contextual events affect preference? In this study, three tests were applied to assert whether contextual unpredictability has a negative effect on preference for novel visual items. By asking subjects to rate their first impressions of novel brand logos while playing simple sounds, Study 1 shows that brand logos coupled to unpredictable sounds were rated less favorabl...
