The present study examined the role of an amygdalo-nigrostriatal pathway in associative learning. An asymmetrical lesion model was used to test whether a circuit from the amygdala central nucleus to the dorsolateral striatum, via the substantia nigra, is critical for mediating conditioned orienting responses. Rats with an asymmetrical lesion, consisting of neurotoxic removal of central nucleus ...

To optimise speed and accuracy of motor behaviour, we can prepare not only the type of movement to be made but also the time at which it will be executed. Previous cued reaction-time paradigms have shown that anticipating the moment in time at which this response will be made ("temporal orienting") or selectively preparing the motor effector with which an imminent response will be made (motor i...

Background & Aims: The quality of interaction between mother and infant has an important role in the formation of infant's personality, social and cognitive functions, temperament and mental health in future. The quality of this reaction is not predictable and can be improved along the time. Thus, Knowing effective variables in this area can be very beneficial in its improvement. Method: In the...

Links between marital aggression and infant orienting toward mother in fearful and frustrating contexts were examined in 92 mother-infant dyads when infants were six months. Results demonstrated that marital aggression was linked with less orienting toward mothers in frustrating situations, in fearful situations marital aggression was linked with less orienting among infants who were high on fe...

The mechanisms that underlie the control of visuospatial attention determine where we look at any moment. During everyday vision, the sudden appearance of a visual stimulus can “capture” attention (Godijn & Theeuwes, 2002), which can initially facilitate orienting to that location, but later may inhibit orienting to that location. These reflexive, covert orienting behaviors have been termed Att...

Mindless eating, or eating while distracted by surrounding stimuli, leads to overeating. The present study explored whether "mindless feeding," or maternal distraction during bottle-feeding, is associated with greater infant formula/milk intakes and lower maternal sensitivity to infant cues. Mothers and their ≤24-week-old bottle-feeding infants (N = 28) visited our laboratory for a video-record...

BACKGROUND Attentional deficits in Autism spectrum disorder (ASD) are often noted, but their specific nature remains unclear. OBJECTIVE The present study used the child Attentional Network Task (Child ANT) in combination with functional magnetic resonance imaging (fMRI) to determine if the consistently cited deficits of orienting attention are truly due to dysfunctions of orienting-based netw...

Recent behavioral data have shown that central nonpredictive gaze direction triggers reflexive shifts of attention toward the gazed-at location (e.g., Friesen & Kingstone, 1998). Friesen and Kingstone suggested that this reflexive orienting effect is unique to biologically relevant stimuli. Three experiments were conducted to test this proposal by comparing the attentional orienting produced by...

The voluntary and reflexive orienting abilities of persons with Down syndrome and fragile X syndrome, at average MA levels of approximately 4 and 7 years, were compared with an RT task. Reflexive orienting abilities appeared to develop in accordance with MA for the participants with Down syndrome but not for those with fragile X syndrome. However, both groups showed delayed voluntary orienting....
