Sensitization and habituation regulate reinforcer effectiveness 总被引:1,自引:1,他引:0
We argue that sensitization and habituation occur to the sensory properties of reinforcers when those reinforcers are presented repeatedly or for a prolonged time. Sensitization increases, and habituation decreases, the ability of a reinforcer to control behavior. Supporting this argument, the rate of operant responding changes systematically within experimental sessions even when the programmed rate of reinforcement is held constant across the session. These within-session changes in operant responding are produced by repeated delivery of the reinforcer, and their empirical characteristics correspond to the characteristics of behavior undergoing sensitization and habituation. Two characteristics of habituation (dishabituation, stimulus specificity) are particularly useful in separating habituation from alternative explanations. Arguing that habituation occurs to reinforcers expands the domain of habituation. The argument implies that habituation occurs to biologically important, not just to neutral, stimuli. The argument also implies that habituation may be observed in “voluntary” (operant), not just in reflexive, behavior. Expanding the domain of habituation has important implications for understanding operant and classical conditioning. Habituation may also contribute to the regulation of motivated behaviors. Habituation provides a more accurate and a less cumbersome explanation for motivated behaviors than homeostasis. Habituation also has some surprising, and easily testable, implications for the control of motivated behaviors. 相似文献

This article provides an overview of parent management training (PMT) for preschool-age children with aggressive and oppositional behaviors. Assessment strategies and basic concepts of PMT are provided. Theoretical underpinnings and research outcomes are highlighted for some variations of PMT programs that have strong empirical support. These programs include Helping the Noncompliant Child, Parent–Child Interaction Therapy, Incredible Years Training Series, Triple P-Positive Parenting Program, and Oregon Early Intervention Foster Care. 相似文献

Gaze following allows individuals to detect the locus of attention of both conspecifics and other species. However, little
is known about how this ability develops. We explored the emergence of bobwhite quail hatchlings’ ability to track human gaze
by assessing their avoidance behavior in an open arena under five testing conditions: (1) a Direct Gaze condition, in which
an experimenter looking down was positioned above one of two approach areas; (2) a Gaze Follow condition in which an experimenter,
positioned equidistant between two approach areas, directed his/her gaze towards one of the areas; (3) a Masked Gaze Follow
condition, in which the experimenter wore a mask during the Gaze Follow test; (4) a Deprived Face Experience condition, in
which hatchlings were deprived of experience with human faces prior to the Gaze Follow test; and (5) a Control condition in
which no experimenter was present during testing. Results revealed that hatchlings from the Direct Gaze condition preferred
the non-gazed approach area at all ages tested. Hatchlings from the Gaze Follow condition preferred the non-gazed approach
area at 48 and 72 h, but not at 24 h of age. In contrast, hatchlings from the Masked Gaze Follow, Deprived Face and Control
conditions did not prefer either approach area at any age tested. These results indicate that experience with human faces
plays a key role in the rapid emergence of gaze following behavior in bobwhite quail hatchlings. 相似文献

心理学视野中的社会排斥 总被引:4,自引:1,他引:3
社会排斥是许多社会问题的深层根源,长期为社会学者、政策研究者所关注。近年来,心理学者也将目光转向了社会排斥研究。在心理学者的视野中,社会排斥是指个体被某一社会团体或他人排斥或拒绝,一个人的归属需求和关系需求受到阻碍的现象。文章主要介绍了社会排斥影响个体认知、情绪和行为的研究。文章认为,在我国开展社会排斥的心理学研究,很有现实意义 相似文献

This study was aimed at uncovering physical and geometric properties that make a particular landmark a target of exploration
and navigation. Rats were tested in a square open-field arena with additional portable corners featuring the same properties
as the arena corners. It was found that the routes of progression converged upon the added corners, whether located at the
arena wall or the arena center. Route convergence upon the added corners involved numerous visits to these corners. However,
time spent at the added corners was relatively short compared with the arena corners, including that from which rats were
introduced into the arena. There was no differential effect of testing rats in light or dark, or with a low versus a high
portable corner. It is suggested that the added corners were distinct against the background of the arena enclosure, whereas
the four arena corners and walls were encoded by the rats as one geometric module. This distinctness, together with the greater
accessibility of the added corners, made them salient landmarks and a target of exploration. Thus, the impact of a landmark
extended beyond its specific self-geometry to include accessibility and distinctness, which are contextual properties. In addition to the contextual impact on locomotor behavior there was also a temporal effect,
with security initially dominating the rats’ behavior but then declining along with an increased attraction to salient landmarks.
These spatiotemporal patterns characterized behavior in both lit and dark arenas, indicating that distal cues were secondary
to local proximal cues in shaping routes. 相似文献

The aim of the present study was to investigate Type A behavior as well as perceived work situation, and associations with burnout and work engagement. The associations in focus were investigated through hierarchical regressions in a sample (N= 329) of Swedish Information Communication Technology consultants. The findings indicated that both work situation and Type A behavior was correlated with work engagement and burnout; however, no interactions between Type A behavior and work situation were elicited. The main conclusion was that the achievement striving aspect of Type A behavior appears as "non-toxic" and is related only to work engagement. However, the irritability/impatience aspect appears to be responsible for burnout complaints among Type A individuals, possibly through negative effects of the mood itself than through perceived stress at work. 相似文献

The present meta-analytic review aimed to clarify divergent findings concerning the relation between reactive and proactive aggression in children and adolescents. Fifty-one studies with 17,965 participants were included in the analysis. A significant correlation between reactive and proactive aggression was found. The strength of this relation varied considerably between studies, from -.10 to .89. Observational assessment and tilt/noise tasks were associated with smaller correlations than questionnaires. Within the large group of questionnaire studies, studies disentangling the form and function of aggression found lower correlations than studies that did not disentangle form and function. Among questionnaire studies, higher reliability was associated with larger correlations. Effect size did not depend on other study characteristics such as sample type, age, and informant type. It is concluded that reactive and proactive aggression are most clearly distinguished with behavioral observations and questionnaires that unravel form and functions of aggression. 相似文献
