The Generality Constraint and Categorial Restrictions

We should not admit categorial restrictions on the significance of syntactically well formed strings. Syntactically well formed but semantically absurd strings, such as 'Life's but a walking shadow' and 'Caesar is a prime number', can express thoughts; and competent thinkers both are able to grasp these and ought to be able to. Gareth Evans' generality constraint, though Evans himself restricted it, should be viewed as a fully general constraint on concept possession and propositional thought. For (a) even well formed but semantically cross-categorial strings often do possess substantive inferential roles; (b) hearers exploit these inferential roles in interpreting such strings metaphorically; (c) there is no good reason to deny truth-conditions to strings with inferential roles.     

Biological bases of face preference in 6-week-old infants

Six-week-old infants (N =40) who started the experiment in either a calm or crying state, received sucrose from an experimenter, while in eye contact with her. Sucrose was delivered either by syringe or on a pacifier. After 3.5 min., the experimenter retired, the mother came into the test room and placed her infant over her shoulder en face with a video camera. The experimenter and a confederate, both dressed identically, sat in front of and slightly to either side of the infant and the infant could choose to look at either experimenter. To minimize position bias, experimenters switched sides every 30 sec. To maintain a stable level of infant attention, they simultaneously called the baby's name at 10 sec. intervals. When an infant looked at one or the other experimenters, she raised her thumb in camera view. Only crying infants who sucked a sweet pacifier showed a preference for their experimenter. As a group none of the other infants did so. However, there was a wide distribution of sucking times in calm week 6 infants. Choice was linearly related to sucking duration. Infants who sucked for substantial periods of time, showed a strong preference for the experimenter. Those who sucked for minimal periods of time strongly preferred the confederate. Based on these findings and ones from 9- and 12-week-old infants, a model is presented in which preference in this experimental paradigm is determined by idealized levels of central activation. These levels may be inferred from the normal crying function at a particular age.     

Identifying Beneficial Physical Activity During School Recess: Utility and Feasibility of the Fitbit

The purpose of the current study was to assess the utility, feasibility, and reliability of Fitbit accelerometers to measure physical activity (via steps) of 15 young children simultaneously during recess. Fitbit-recorded steps per minute (SPM) were used as the primary measure to assess levels of activity in children playing in various structured (i.e., instructed) and unstructured (i.e., free play) recess activities. The results suggested that the number of steps measured by two Fitbits resulted in high levels of agreement, and the Fitbits were successful at identifying differential levels of activity across multiple types of play activities. Across all children, running or walking was associated with the most SPM (M = 89) and highest percentage of moderate-to-vigorous physical activity (MVPA; M = 47%), followed by soccer (M = 58 SPM; M = 12% MVPA), free play (M = 53 SPM; 3% MVPA), and tag (M = 43 SPM; 7% MVPA). The utility of the Fitbit’s minute-by-minute data records was demonstrated, with the use of additional third-party software by Python, as differential levels of physical activity associated with various play behaviors were detected, and all 15 participants were assessed simultaneously with very few observers.     

Is the moral domain unique? A social influence perspective for the study of moral cognition

The nature of the cognitive processes that give rise to moral judgment and behavior has been a central question of psychology for decades. In this paper, we suggest that an often ignored yet fruitful stream of research for informing current debates on the nature of moral cognition is social influence. We introduce what we call the “social‐moderation‐of‐process” perspective, a methodological framework for leveraging insights from social influence research to inform debates in moral psychology over the mechanisms underlying moral cognition and the moral domains in which those mechanisms operate. We demonstrate the utility of the social‐moderation‐of‐process perspective by providing a detailed example of how research on social influence in behavioral ethics can be utilized to test a research question related to a debate between two prominent theories in moral psychology. We then detail how researchers across the field of moral psychology can utilize our social‐moderation‐of‐process perspective.     

Object substitution masking and its relationship with visual crowding

Object substitution masking (OSM) occurs when the perceptibility of a brief target is reduced by a trailing surround mask typically composed of four dots. Camp et al. (Journal of Experimental Psychology: Human Perception and Performance, 41, 940–957, 2015) found that crowding a target by adding adjacent flankers, in addition to OSM, had a more deleterious effect on performance than expected based on the combined individual effects of crowding and masking alone. The current experiments test why OSM and crowding interact in this way. In three experiments, target-flanker distance is manipulated whilst also varying mask duration in a digit identification task. The OSM effect—as indexed by the performance difference between unmasked and masked conditions—had a quadratic function with respect to target-flanker distance. Results suggest it is OSM affecting crowding rather than the converse: Masking seems to amplify crowding at intermediate target-distractor distances at the edge of the crowding interference zone. These results indicate that OSM and crowding share common mechanisms. The effect of OSM is possibly a consequence of changes to the types of feature detectors which are pooled together for target identification when that target must compete for processing with a trailing mask in addition to competition from adjacent flankers.     

Blind ethics: Closing one's eyes polarizes moral judgments and discourages dishonest behavior

Four experiments demonstrate that closing one’s eyes affects ethical judgment and behavior because it induces people to mentally simulate events more extensively. People who considered situations with their eyes closed rather than open judged immoral behaviors as more unethical and moral behaviors as more ethical. In addition, considering potential decisions with closed eyes decreased stated intentions to behave ethically and actual self-interested behavior. This relationship was mediated by the more extensive mental simulation that occurred with eyes closed rather than open, which, in turn, intensified emotional reactions to the ethical situation. We discuss the implications of these findings for moral psychology and ethical decision making.     

Keeping the illusion of control under control: Ceilings, floors, and imperfect calibration

Prior research has claimed that people exaggerate probabilities of success by overestimating personal control in situations that are heavily or completely chance-determined. We examine whether such overestimation of control persists in situations where people do have control. Our results suggest a simple model that accounts for prior findings on illusory control as well as for situations where actual control is high: People make imperfect estimates of their level of control. By focusing on situations marked by low control, prior research has created the illusion that people generally overestimate their level of control. Across three studies, we show that when they have a great deal of control, people under-estimate it. Implications for research on perceived control and co-variation assessment are discussed.     

Bringing ethics into focus: How regulatory focus and risk preferences influence (Un)ethical behavior

In four laboratory studies, we find that regulatory focus induced by situational cues (such as the framing of an unrelated task) or primed influences people’s likelihood to cross ethical boundaries. A promotion focus leads individuals to be more likely to act unethically than a prevention focus (Studies 1, 2, and 3). These higher levels of dishonesty are explained by the influence of a person’s induced regulatory focus on his or her behavior toward risk. A promotion focus leads to risk-seeking behaviors, while a prevention focus leads to risk avoidance (Study 3). Through higher levels of dishonesty, promotion focus also results in higher levels of virtuous behavior (Studies 2 and 3), thus providing evidence for compensatory ethics. Our results also demonstrate that the framing of ethics (e.g., through an organization’s ethics code) influences individuals’ ethical behavior and does so differently depending on an individual’s induced regulatory focus (Study 4).     

Ethnic differences in clinical presentation of depression in adult women

This study examined ethnic differences in self-report and interviewer-rated depressive symptoms and estimated the contributions of sociodemographic and psychosocial factors in predicting severity of depression. One hundred twenty-five clinically depressed African American (n = 46), Caucasian (n = 36), and Latina (n = 43) women were recruited. After controlling for differences in socioeconomic status, African American women reported more symptoms of distress and Latinas were rated as significantly more depressed than the other groups. However, these ethnic differences were not moderated by either education or employment. Finally, hierarchical regression analysis indicated that severity of depression was predicted by low education, being single, being Latina, high perceived stress, and feelings of hopelessness. Additional research is needed to validate these results and to investigate their clinical significance.     

Further analysis of idiosyncratic antecedent influences during the assessment and treatment of problem behavior

Recent research findings suggest that idiosyncratic variables can influence the outcomes of functional analyses (E. G. Carr, Yarbrough, & Langdon, 1997). In the present study, we examined idiosyncratic environment-behavior relations more precisely after identifying stimuli (i.e., a particular toy and social interaction) associated with increased levels of problem behavior. Two children, an 8-year-old boy with moderate mental retardation and a 5-year-old boy with no developmental delays, participated. Results of functional analyses for both children indicated that idiosyncratic antecedent stimuli set the occasion for occurrences of problem behavior (hand biting or hand flapping) and that problem behavior persisted in the absence of social contingencies. Further analyses were conducted to identify specific components of the stimuli that occasioned problem behavior. Treatments based on results of the analyses successfully reduced self-injury and hand flapping.
