The Contribution of the Dyadic Parent-Child Interaction Coding System (DPICS) Warm-Up Segments in Assessing Parent-Child Interactions

This study evaluated the inclusion of uncoded segments in the Dyadic Parent-Child Interaction Coding System, an analogue observation of parent-child interactions. The relationships between warm-up and coded segments were assessed, as well as the segments’ associations with parent ratings of parent and child behaviors. Sixty-nine non-referred parent-child dyads engaged in the observation. Parents completed measures about their parenting and children's behaviors. Significant differences were observed between the first situation's warm-up and coded segments, whereas minimal differences were found for the second situation. Findings suggest that the second warm-up segment may not be necessary for optimal assessment of parent-child interactions.     

Measuring Change During Behavioral Parent Training Using the Parent Instruction-Giving Game with Youngsters (PIGGY): A Clinical Replication

This is the second study to investigate the clinical use of the Parent-Instruction Game with Youngsters (PIGGY) which is a structured observation system derived from the Dyadic Parent-Child Interaction Coding System II (DPICS-II; Eyberg, Bessmer, Newcomb, Edwards, & Robinson, 1994) and the Behavior Coding System (BCS; Forehand & McMahon, 1981 Forehand , R. L. , & McMahon , R. J. ( 1981 ). Helping the noncompliant child . New York , NY : Guilford Press . [Google Scholar]). In a previous study, the PIGGY demonstrated strong reliability and validity as well as clinical utility (Hupp, Reitman, Forde, Shriver, & Kelley, 2008). The present study is a replication of the previous research on clinical utility by using the PIGGY to monitor changes in parent and child behavior during and after behavioral parent training.     

Schema Theory: A Critical Appraisal and Reevaluation

The authors replicated and extended results from the gunfight paradigm (A. Welchman, J. Stanley, M. Schomers, R. Miall, & H. Bulthoff, 2010a) in which participants moved faster when reacting to the perceived initiation of an opponent compared to initiating an action themselves. In addition to replicating these movement time effects, the authors found that time to peak velocity, peak velocity, and movement-endpoint dispersions were similarly impacted. The findings are discussed in terms of a triggering mechanism involved in ballistic and internally generated movements.     

Interference Effects from Observed Movement in Parkinson's Disease

Previous research has demonstrated that Parkinson's disease patients have an increased susceptibility to response conflict. In the present study, the authors investigate whether Parkinson's patients have a similar sensitivity to interference from observed movements. In all, 10 patients and 10 controls performed horizontal and vertical arm movements while watching a video of either a person performing similar movements or a moving dot. Movements were performed in the same plane (congruent) and orthogonal to the observed movement (incongruent). The off-axis variance of movements was our index of interference. Although patients tended to exhibit more off-axis variability than did controls, both groups demonstrated similar congruence effects, with greater variance in incongruent conditions. These results indicated that increased susceptibility to interference in Parkinson's disease does not extend to interference from observed movements.     

When far becomes near: Shared environments activate action simulation

It has been proposed that one means of understanding a person's current behaviour and predicting future actions is by simulating their actions. That is, when another person's actions are observed, similar motor processes are activated in the observer. For example, after observing a reach over an obstacle, a person's subsequent reach trajectory is more curved, reflecting motor priming. Importantly, such motor states are only activated if the observed action is in near (peripersonal) space. However, we demonstrate that when individuals share action environments, simulation of another person's obstacle avoiding reach path takes place even when the action is in far (extrapersonal) space. We propose that action simulation is influenced by factors such as ownership. When an “owned” object is a potential future obstacle, even when it is viewed beyond current action space, simulations are evoked, and these leave a more stable memory capable of influencing future behaviour.     

The intentionality bias and schizotypy

The “intentionality bias” refers to our automatic tendency to judge other people's actions to be intentional. In this experiment we extended research on this effect in two key ways. First, we developed a novel nonlinguistic task for assessing the intentionality bias. This task used video stimuli of ambiguous movements. Second, we investigated the relationship between the strength of this bias and schizotypy (schizophrenia-like symptoms in healthy individuals). Our results showed that the intentionality bias was replicated for the video stimuli and also that this bias is stronger in those individuals scoring higher on the schizotypy rating scales. Overall these findings lend further support for the existence of the intentionality bias. We also discuss the possible relevance of these findings for our understanding of certain symptoms of schizophrenic illness.     

Sun protection behaviour of children and their parents at the beach

Abstract

The present study observed the sun protection behaviour of 8–12 year old children and their parents on the beach. Interviews with children and parents were then conducted to examine possible influences on sun protection and the relationship between observed and self reported behaviour.

The sample consisted of 50 children and 68 parents. All 50 children were observed and interviewed. All the parents were observed and 33 were interviewed. Indices of sun protection cover were computed as a sum of clothing and sunscreen cover. Most parents and children were inadequately covered against the sun. Factors related to children's sun protection included parent's cover and the child's tan level. The relationship between attitude to sun protection and observed behaviour could not be examined as all children and parents indicated they thought it was important to protect their skin against the sun.

Inconsistencies between observed and self-reported sun protection were found for children who were not protecting themselves. The possibility that self-report may overestimate actual protective behaviour is discussed.     

Proneness for exercise,cognitive and psychophysiological consequences of action observation

ObjectivesPhysical exercise has benefits that go beyond health and well-being, namely in cognitive, motor and psychophysiological areas. The discovery of a shared neural network between action observation and execution (Action-Observation Network) led us to hypothesize that watching human motor action might improve cognitive and motor aspects of performance and proneness for exercise.Design/MethodsSixty participants viewed a Motor (M) (n = 30) or a Non-Motor (NM) (n = 30) movie with strong or weak content of motoric features of human action, respectively. Performance in d2 Attention test, Fitts' Motor task, and a Proneness for Exercise Visual Analog Scale was assessed before and after movie visualization, in a cross-sectional study. Psychophysiological measures were recorded throughout the experiment.ResultsOur results demonstrate an increase in proneness for exercise, and greater improvement in attention-related cognitive aspects in the M group. The aforementioned benefits of action observation did not modulate motor performance. A mental effort deployment was associated to the decrease in heart rate variability after visualization of the NM movie. This was not conducive to attention channeling on task performance. Conversely, M movie observation seemed to be associated to a cognitive load release, affording attention deployment for the resolution of the subsequent tasks.ConclusionsIt seems that some benefits associated to physical practice can result from the mere visualization of movies with human motor action content. These are the improvement in attention-related cognitive skills associated to psychophysiological changes that support a disengagement from mental effort. Crucially, the observation of exercise behavior seems to be a key factor for exercise adherence.     

THE INTERPLAY OF DEDUCTIVE AND INDUCTIVE REASONING IN PSYCHOANALYTIC THEORIZING

Deductive and inductive reasoning both played an essential part in Freud's construction of psychoanalysis. In this paper, the author explores the happy marriage of empiricism and rationalism in Freud's use of deductive reasoning in the construction of psychoanalytic theory. To do this, the author considers three major amendments Freud made to his theory: (i) infant and childhood sexuality, (ii) the structural theory, and (iii) the theory of signal anxiety. Ultimately, the author argues for, and presents Freud as a proponent of, the epistemological position that he calls critical realism.
