Harming is more intentional than helping because it is more probable: the underlying influence of probability on the Knobe effect

Knobe [2003. Intentional action and side effects in ordinary language. Analysis, 63, 190–194] demonstrated that people’s intentionality judgments in side effects depend on the outcome of the side-effect, indicating that people’s judgments of intentionality of action depend on not only the intention of the actor but also on the result of the action. However, on the basis of findings in judgment and decision making, the current study proposes another hypothesis to Knobe’s (2003) results: the participants’ intentionality judgments are related to not only the outcomes themselves but also the probabilities of outcomes predicted from the action. To test this hypothesis, the present study employed an identical experimental procedure to Knobe (2003), except that it required not only intentionality but also probability judgments for outcomes that resulted from the actions of a company president. The results replicated the findings of Knobe (2003) and showed a relationship between probability and intentionality judgment.     

Perseverative errors in object discrimination learning by aged Japanese monkeys (Macaca fuscata).

To examine the nature of age-dependent cognitive decline, performance in terms of concurrent object discriminations was assessed in aged and nonaged Japanese monkeys (Macaca fuscata). Aged monkeys required more sessions and committed more errors than nonaged ones in the discriminations, even in simple object discriminations. Analyses of errors suggest that aged monkeys repeated the same errors and committed more errors when they chose a negative object at the 1st trial. A hypothesis analysis of behavior suggests that their incorrect choices were mainly due to object preference. Therefore, the impairment was probably caused by a failure to inhibit inappropriate responses. Together with previous neuropsychological findings, deficits of aged monkeys in the performance of object discriminations can be explained by dysfunction of the frontal cortex.     

Effects of workshop trainings on evidence-based practice knowledge and attitudes among youth community mental health providers

Enhancing the public health impact of evidence-based practices (EBPs) in usual care settings is a key priority of the National Institute of Mental Health. Longitudinal data from community mental health providers (N = 268) participating in a series of state-sponsored workshops in modular approaches to EBPs for youth are presented. EBP workshop attendance for youth anxiety resulted in increased knowledge for EBPs for anxiety (and not other conditions) and EBP workshop attendance for youth disruptive behaviors resulted in increased knowledge for EBPs for disruptive behaviors (and not other conditions). Providers' tendencies toward incorrectly classifying non-EBP therapies as evidence-based increased over time, suggesting that providers over-generalize the EBP label as a result of attending these types of workshops. Regarding EBP attitudes, most measures of attitudes improved when providers attended a workshop. Additionally, an overly inclusive view of what constitutes an EBP at intake was related to significant decreases in openness to trying EBPs over time, whereas more positive attitudes at intake was related to achieving a more refined view of what constitutes an EBP over the course of attending trainings. Study limitations and implications for implementation of EBPs in usual care settings are discussed.     

Immediate use of prosody and context in predicting a syntactic structure

Numerous studies have reported an effect of prosodic information on parsing but whether prosody can impact even the initial parsing decision is still not evident. In a visual world eye-tracking experiment, we investigated the influence of contrastive intonation and visual context on processing temporarily ambiguous relative clause sentences in Japanese. Our results showed that listeners used the prosodic cue to make a structural prediction before hearing disambiguating information. Importantly, the effect was limited to cases where the visual scene provided an appropriate context for the prosodic cue, thus eliminating the explanation that listeners have simply associated marked prosodic information with a less frequent structure. Furthermore, the influence of the prosodic information was also evident following disambiguating information, in a way that reflected the initial analysis. The current study demonstrates that prosody, when provided with an appropriate context, influences the initial syntactic analysis and also the subsequent cost at disambiguating information. The results also provide first evidence for pre-head structural prediction driven by prosodic and contextual information with a head-final construction.     

The Early Lives of Highly Creative Persons: The Influence of the Complex Family

Over the last 50 years, theoretical, speculative, and empirical scholarship has examined the influence of early family context on subsequent accomplishments in children of high ability. Building upon 40 years of creativity literature focusing on optimal experience, this exploratory study applied the Complex Family Framework in a systematic analysis of creative adults' recollections of their early family lives. The study identifies evidence of the interplay of Integration and Differentiation, a catalyst for individual optimal experience, in the families of 9 creative exemplars who have made significant contributions to contemporary culture. Five participants represented the Arts and Humanities, three the Social Sciences, and one the Physical Sciences. The study demonstrates the utility of the Complex Family Framework in understanding families' contributions to children's later creative achievement.     

Slower Reorientation of Trunk for Reactive Turning while Walking in Hemiparesis Stroke Patients

We examined the behavioral characteristics of reactive turning in hemiplegic stroke patients when they were informed of the turning direction just before turning was required at an unpredictable time. Eleven stroke patients and 20 healthy elderly control people were asked to initiate a turn as soon as a visual cue to inform them of the turning direction was activated unpredictably using a foot switch. Both the segmental reorientation and stepping type when turning 90° while walking were measured. The results indicated preserved segmental reorientation of the head and pelvis in stroke patients. Stroke patients showed delays in pelvic turning but not in head turning. Their delayed pelvic movement might be due to motor dysfunction and the time taken to ensure stability when deciding when to turn.     

Deterioration of planning ability with age in Japanese monkeys (Macaca fuscata)

To investigate the ability of aged monkeys to plan and the effect of aging on this ability, performance in a food retrieval task was assessed in aged and younger Japanese monkeys (Macaca fuscata). In this task, the monkeys had to retrieve food items by selecting from a set of 9 holes, each of which contained 1 food item. Results showed that task performance declined significantly with age. All monkeys showed, to a greater or lesser extent, some consistent patterns in their sequence of selecting holes for retrieving the food item. An analysis of these selection patterns indicated that the younger monkeys showed more consistent sequences in selection than the aged monkeys. Furthermore, success in the task performance correlated strongly with higher consistency in the sequence of selecting holes. The authors simulated performance for this task by monkeys without any strategies or plans. The results suggest that the empirical data were far more systematic than the simulated data. Thus, the authors conclude that Japanese monkeys have the ability to plan and that this ability to plan deteriorates with age.     

Choice reaction time of elbow flexion and extension during passive elbow motions

The effect of passive elbow motions on electromyographic reaction times (EMG-RTs) of the biceps brachii for elbow flexion and the triceps for elbow extension was investigated in 8 normal subjects, using a choice-RT task, in which the subject was uncertain about the response direction to perform until the arrival of response signal after the passive motion started. Compared to the static condition, choice EMG-RTs shortened only when the direction of passive and response movements was the same. It seems that passive motions act as prior information on direction of movement in the choice-RT task.     

Relative contributions of expressive behavior and contextual information to the judgment of the emotional state of another

This study used a technique for assessing the relative impact of facial-gestural expressions, as opposed to contextual information regarding the elicitor and situation, on the judgment of emotion. In Study 1, 28 undergraduates rated videotapes of spontaneous facial-gestural expressions and separately rated the emotionally loaded color slides that elicited those expressions. The source clarities of the expressions and slides were matched using correlation and distance measures, and 18 expressions and 9 slides were selected. In Study 2, 72 undergraduate receivers were shown systematic pairings of these expressions and slides and rated the emotional state of the expresser, who was supposedly watching that slide under public or private situational conditions. Expressions were found to be more important sources for all emotion judgments. For female receivers slides were relatively more important in the public than in the private situation.
