The role of goal-directed behavior in intention attribution in children

In this study, we addressed the question of the nature of the information needed by 13-month-old infants to understand another agent's intentions. In two experiments, an experimenter was either unable or unwilling to give a toy to an infant. Importantly, an implement (a gutter in which the toy could roll down toward the infant) was used to make the experimenter's behavior as similar as possible in the two conditions. When the experimenter remained still in both conditions, infants did not behave differently according to the experimenter's intentions, suggesting that they did not infer them. By contrast, in a second experiment, where the experimenter performed an action directed toward the gutter in both conditions, the infants looked away from the experimental setting more often and longer in the unwilling condition than in the unable condition. They also looked more toward the experimenter in the unable condition than in the unwilling condition. Therefore, we conclude that an agent's intentional attitude can already be inferred by a 13-month-old provided that this intention is concretely shown through a goal-directed action.     

Neural and Pavlovian influences on immunity

The traditional view that the nervous and immune systems are functionally independent (aside from general stress effects and autoimmune disorders of the nervous system) is being challenged by a new view that the nervous system regulates the activity of the immune system. If this is true, it should be possible to change the activity of the immune system by means of Pavlovian conditioning, just as it is possible to condition other physiological events influenced by the autonomic nervous system or neuroendocrine substances. Evidence for autonomic and neuroendocrine modulation of immune activity is briefly reviewed; and, the various studies reporting conditioned immune effects, the physiological mechanisms most likely involved, and their possible significance are discussed.     

On insirumental response interaction as explaining the influences of Pavlovian CSs upon avoidance behavior

The finding that Pavlovian signals for food or shock influence avoidance responding might be explained either by interaction of conditioned central mediational states or interaction of learned instrumental responses. Using three groups of dogs, the two hypotheses were pited one against the other in a three-stage transfer-of-control experiment. In the initial conditioning phase, tones were established as signals for food, shock, or neither; additionally the tones also cued a common instrumental response. Following avoidance training, the tone was tested for its influence upon avoidance. If the lone had signaled food, avoidance was suppressed; if shock, avoidance was facilitated; if neither, avoidance was unaffected. This was interpreted as supporting the hypothesis that interaction of central states mediates the transfer-of-control.     

Enjoying goal-directed action: the role of regulatory fit

We propose that the fit between an action's strategic orientation and the actor's regulatory state can influence the amount of enjoyment the action provides. In two studies using different methods of manipulating regulatory states and of gauging action evaluations, high regulatory fit increased participants' anticipations of action enjoyability. In a third study, high regulatory fit increased participants' enjoyment of, perceived success at, and willingness to repeat a novel laboratory task, and these effects were independent of participants' actual success on the task. Across the three studies, participants in a regulatory state oriented toward accomplishment experienced eagerness-related actions more favorably than vigilance-related actions, whereas participants in a regulatory state oriented toward responsibility experienced vigilance-related actions more favorably than eagerness-related actions. These findings' implications for understanding task interest and motivation are discussed.     

Habits as knowledge structures: automaticity in goal-directed behavior

This study tested the idea of habits as a form of goal-directed automatic behavior. Expanding on the idea that habits are mentally represented as associations between goals and actions, it was proposed that goals are capable of activating the habitual action. More specific, when habits are established (e.g., frequent cycling to the university), the very activation of the goal to act (e.g., having to attend lectures at the university) automatically evokes the habitual response (e.g., bicycle). Indeed, it was tested and confirmed that, when behavior is habitual, behavioral responses are activated automatically. In addition, the results of 3 experiments indicated that (a) the automaticity in habits is conditional on the presence of an active goal (cf. goal-dependent automaticity; J. A. Bargh, 1989), supporting the idea that habits are mentally represented as goal-action links, and (b) the formation of implementation intentions (i.e., the creation of a strong mental link between a goal and action) may simulate goal-directed automaticity in habits.     

The role of verbal behavior in the establishment of comparative relations

Twelve college students received conditional discrimination training with nonarbitrary and arbitrary stimuli, and derived comparative and transformation of function tests with a think-aloud condition across 2 experiments. Participants who failed these tests received remedial verbal operant training. Four control participants received verbal operant training alone. Across both experiments, only 1 participant passed the derived comparative test after conditional discrimination training. However, all participants passed derived comparative tests and 11 out of 12 participants passed transformation of function tests following verbal operant training, including the 4 control participants. Participants who passed derived comparative tests engaged in a high percentage of correct vocalizations during the think-aloud condition, while participants who failed did not. These results suggest that mediating verbal behavior could have played a crucial role in participants' responses during derived stimulus relations tests.     

Longitudinal effects of theory of mind on later peer relations: the role of prosocial behavior

Children's peer relations represent a key aspect of school adjustment. However, little is known about their social-cognitive precursors. To address this gap, the authors followed 70 children across the transition to primary school. At Time 1 (age 5), Time 2 (age 6), and Time 3 (age 7), children were assessed on their theory of mind, prosocial behavior, and verbal ability. In addition, at Time 2 and at Time 3, the authors gathered peer nominations. Results supported the authors' mediational hypothesis of indirect paths from early theory of mind to subsequently lower peer rejection and higher peer acceptance, via improvements in prosocial behavior. The authors discuss implications of these longitudinal effects for the understanding of the impact of social-cognitive achievements for children's developing social relations.     

Pavlovian feed-forward mechanisms in the control of social behavior

The conceptual and investigative tools for the analysis of social behavior can be expanded by integrating biological theory, control systems theory, and Pavlovian conditioning. Biological theory has focused on the costs and benefits of social behavior from ecological and evolutionary perspectives. In contrast, control systems theory is concerned with how machines achieve a particular goal or purpose. The accurate operation of a system often requires feed-forward mechanisms that adjust system performance in anticipation of future inputs. Pavlovian conditioning is ideally suited to subserve this function in behavioral systems. Pavlovian mechanisms have been demonstrated in various aspects of sexual behavior, maternal lactation, and infant suckling. Pavlovian conditioning of agonistic behavior has been also reported, and Pavlovian processes may likewise be involved in social play and social grooming. Several further lines of evidence indicate that Pavlovian conditioning can increase the efficiency and effectiveness of social interactions, thereby improving their cost/benefit ratio. We extend Pavlovian concepts beyond the traditional domain of discrete secretory and other physiological reflexes to complex real-world behavioral interactions and apply abstract laboratory analyses of the mechanisms of associative learning to the daily challenges animals face as they interact with one another in their natural environments.     

Demystifying the role of emotion in behaviour: toward a goal-directed account

ABSTRACT

The paper sketches the historical development from emotion as a mysterious entity and the source of maladaptive behaviour, to emotion as a collection of ingredients and the source of also adaptive behaviour. We argue, however, that the underlying mechanism proposed to take care of this adaptive behaviour is not entirely up for its task. We outline an alternative view that explains so-called emotional behaviour with the same mechanism as non-emotional behaviour, but that is at the same time more likely to produce adaptive behaviour. The phenomena that were initially seen as requiring a separate emotional mechanism to influence and cause behaviour can also be explained by a goal-directed mechanism provided that more goals and other complexities inherent in the goal-directed process are taken into account.     

Past experience influences the processing of stimulus compounds in human Pavlovian conditioning

In two human skin conductance conditioning experiments we investigated whether processing of stimulus compounds can be influenced by past experience. Participants were either pre-trained with a discrimination problem that could be solved elementally (A+, B−, AB+, C− in Experiment 1 and A+, AB+, C−, CB− in Experiment 2) or one that required a configural solution (AB+, BC−, CD+, DA− in Experiment 1 and A−, AB+, C+, CB− in Experiment 2). After pre-training, participants were shown an EX+, FX− discrimination. Subsequently, responding to individual components (E and F) was tested. After elemental pre-training, participants showed larger responses to the component from the previously reinforced compound (E) than to the component from the nonreinforced compound (F) whereas no such difference was found after configural pre-training. This means that the kind of pre-training influenced whether the later discrimination problem was processed elementally or configurally. The results indicate that organisms can flexibly process stimulus compounds in different ways.     

Job search as goal-directed behavior: Objectives and methods

This study investigated the relationship between job search objectives (finding a new job/turnover, staying aware of job alternatives, developing a professional network, and obtaining leverage against an employer) and job search methods (looking at job ads, visiting job sites, networking, contacting employment agencies, contacting employers, and submitting applications). In a sample of 205 employed individuals from Belgium and Romania, job search objectives were significantly related to job search methods even after job satisfaction was controlled. Furthermore, particular objectives predicted specific methods. While the finding a new job/turnover objective predicted all search methods, staying aware of alternatives predicted using job ads and sites; the network objective predicted networking and contacting employers; and the leverage objective predicted contacting employers. Results suggest that search objectives are important for understanding job seekers’ search behavior and support the view that job search is a self-regulatory process that begins with objectives which activate search behavior.     

Pavlovian conditioning in human skilled motor behavior

The role of Pavlovian contingencies in human skilled motor behavior was investigated in three experiments by means of a new conditioning preparation. In Experiment 1 the present method was shown to be appropriate for the study of associative learning. Subjects who experienced a standard delay configuration performed significantly more conditioned responses than subjects who received either backward conditioning or random pairings. Stimulus generalization was shown to be slight in two additional groups. Subsequent experiments examined conditioning with multiple conditioned stimuli (CSs). In particular, in Experiment 2 some reciprocal overshadowing was demonstrated when two conditional stimuli (tone and vibration) were compounded. Experiment 3 investigated blocking. Blocking was less than expected, however. Subjects’ perceptions of the stimuli and reaction time data suggest that a certain proportion had shifted their attention to the added element of the CS compound. Results are discussed in relation to other studies on Pavlovian learning in humans and animals, which are concerned with “stimulus selection.”     

A test for children's goal-directed behavior: a pilot study

A test for children's goal-directed behavior was developed, based on neuropsychological executive function research of Vilkki and Holst and on the framework of Lewin's level-of-aspiration research. 46 12-yr.-old children were participants. Fluid Intelligence was expected to be linked to goal-directed behavior and a commonly used executive function task, the Wisconsin Card-sorting Test. A child was asked to set personal goals in a short-term memory task without prior knowledge about performance. Four different task versions were developed employing both verbal (memorizing series of words) and visuospatial (memorizing block sequences) material. The child set an individual goal for each memory trial. Goal-setting after successful and failed trials was investigated. Usually, the children lowered their goals after failures and set their goals higher or did not change them after successful trials. Compared to goal on a previous trial, Inadequate Responses included setting a goal higher after a failed trial and setting it lower after success. Fluid Intelligence was related to goal-directed behavior, viz., Inadequate Responses. It also correlated with scores on the Wisconsin Card-sorting Test. The results are in concordance with previous research. In addition to experimental executive function research, the novel test might be useful in research concerning children's motivation, self-efficacy, and self-regulated learning.     

Programing of the goal-directed behavior and association systems of the brain

The organism functions in surroundings which are organized according to probability and determine the development of the ability for probabilistic prognosis of goal-directed performance. Probabilistic programing of behavior is assumed to be based on dominant motivation, previous experience (genetic and ontogenetic), and the estimation of the current situation as stored in short-term memory. Association thalamocortical systems of the brain appear to possess basic structural-functional requisites to evaluate their role in the mechanisms of probabilistic prognosis. A hypothetical diagram is given to illustrate the functional structure of a goal-directed behavior based on the dominant mechanisms.     

Infants' imitation of goal-directed actions: the role of movements and action effects

This paper reviews studies on infants' imitation of goal-directed actions in the first two years of life. Special emphasis is given to the role of the two observable components of an action, that is, the movement and the action effects, on infants' replication of target actions. The reviewed studies provide evidence that infants benefit most from a full demonstration of both movements and effects. If movements are demonstrated in isolation, infants may encode this information, but they preferentially reproduce actions that lead to salient effects. If action effects are presented in isolation, infants younger than 19 months usually fail to emulate the unseen movements that would be necessary to produce these effects. Infants' ability to predict action effects or to infer unseen movements from incomplete demonstrations improves substantially at the end of the second year of life. It is concluded that the capability to learn relations between movements and action effects by observation, and the knowledge about movement-effect relations acquired so far, may be important factors underlying the developmental changes in infants' imitation of goal-directed actions.
