Effects of teacher greetings on student on-task behavior

A multiple baseline design across participants was used to determine how teacher greetings affected on-task behavior of 3 middle school students with problem behaviors. Momentary time sampling was used to measure on-task behavior during the first 10 min of class. Teacher greetings produced increases in students' on-task behavior from a mean of 45% in baseline to a mean of 72% during the intervention phase. Teacher greetings represent an antecedent manipulation that can easily be implemented in classrooms to improve students' on-task behavior.     

The Pronoun Attraction Effect for D(iscourse)-Linked Phrases: Evidence from Speakers of a Null Subject Language

Frazier and Clifton (2002) argue that a d(iscourse)-linked wh-phrase such as which boy attracts the reference of a pronoun in a subordinate clause. We translated Frazier and Clifton's materials from English into Romanian. Romanian is a pro-drop language in which null subjects are licensed by person and number agreement on the verb. We found that the d-linking attraction effect held for both pro and overt pronouns in Romanian. The fact that the effect is found for pro provides evidence that the attraction effect is not due to gender matching between the pronoun and the head of the d-linked phrase. We also tested native speakers of Romanian learning English as a second language on Frazier and Clifton's English materials Levels of coreference were highly similar to those for English native speakers and intermediate and advanced learners showed the d-linking attraction effect. We discuss the results in the context of Carminati's (2002) Position of Antecedent Hypothesis, arguing that this hypothesis can account for both the fact that higher levels of coreference with a wh-phrase antecedent were found for pro than for an overt pronoun in Romanian and the fact that the coreference levels between an overt pronoun and the wh-phrase antecedent were not elevated for Romanian-speaking second language learners of English.     

Using simultaneous presentation to increase vegetable consumption in a mildly selective child with autism

A multiple baseline design was used to evaluate the effects of adding condiments on the consumption of previously rejected foods (vegetables). Adding condiments produced increased food acceptance across three food items. Data are discussed in relation to conditioned food preferences and establishing operations.     

Asymmetrical loading affects intersegmental dynamics during the swing phase of walking

Much of the work related to lower extremity inertia manipulations has focused on temporal, kinematic and traditional inverse dynamics assessments during locomotion. Intersegmental dynamics is an analytical technique that provides further insights into mechanisms underlying linked-segment motion. The purpose of this study was to determine how intersegmental dynamics during the swing phase of walking are altered during asymmetrical lower extremity loading. Participants walked overground at a speed of 1.57 m s^?1 with 0, 0.5, 1.0, and 2.0 kg attached to one foot. Net, interaction, gravitational, and muscle moments were computed. Moment magnitudes at joints of the loaded leg increased systematically with increasing load, whereas unloaded leg moments were unaffected by loading. With increasing load, relative contributions of interaction moments about the knee and hip and gravitational moment about the ankle increased (i.e., 21%, 8%, and 44% increases, respectively), whereas the relative contributions of muscle moments about all three joints declined (i.e., ?4%, ?13%, and ?8% decreases for the ankle, knee, and hip, respectively for unloaded vs. 2.0 kg). These results suggest that altered inertia properties of the limb not only affected the amount of muscular effort required to swing the leg, but also changed the nature of the interaction between segments.     

Negative priming and sequence learning

Three experiments used a novel sequence learning task, in which participants responded to changes in location of one visual stimulus whilst ignoring another. Experiment 1 demonstrated negative priming effects in this task, in that responses to individual sequence elements were disrupted when the attended stimulus (e.g., red asterisk) appeared at the location taken by the unattended stimulus (e.g., blue asterisk) on the immediately preceding trial. Experiments 2 and 3 found that negative priming effects extended beyond sensitivity to individual items, suggesting that people may be able to learn about sequential features of ignored events as well as about single events in isolation. The results are discussed in relation to current theories of negative priming.     

Moral responsibility and the problem of manipulation reconsidered

It has been argued that all compatibilist accounts of free action and moral responsibility succumb to the manipulation problem: evil neurologists or their like may manipulate an agent, in the absence of the agent’s awareness of being so manipulated, so that when the agent performs an action, requirements of the compatibilist contender at issue are satisfied. But intuitively, the agent is not responsible for the action. We propose that the manipulation problem be construed as a problem of deviance. In troubling cases of manipulation, psychological elements such as desires and beliefs, among other things, are acquired via causal routes that are deviant relative to causal routes deemed normal or baseline. We develop and defend rudiments of a baseline that is acceptable independently of whether one has compatibilist or incompatibilist leanings.     

Seven Puzzles of Thought and How to Solve Them: An Originalist Theory of Concepts,by Sainsbury,R. M. and Michael Tye

In his 2018 AJP paper, Shlomo Cohen hints that deception could be a distinct subset of manipulation. We pursue this thought further, but by arguing that Cohen’s accounts of deception and manipulation are incorrect. Deception under uncertainty need not involve adding false premises to the victim’s reasoning but it must involve manipulating her response, and cases of manipulation that do not interfere with the victim’s reasoning, but rather utilize it, also exist. Therefore, deception under uncertainty must be constituted by covert manipulation.     

Reflecting on past failures leads to increased perseverance and sustained attention

Psychology has struggled for years to define the traits and tendencies that make an individual successful. Past research has focused on intelligence. Recently, there has been a focus on perseverance or “grit”. We set out to examine the extent to which grit exhibits state-like facets and the relation between manipulations of grit and performance. Results from the first experiment provide evidence that reflecting on failures results in higher grit scores than reflecting on success. The second experiment extends the failure–grit relationship to explore how this relation might modify performance: Encouraging individuals to reflect on failures resulted in a significant reduction in error rates on a cognitive task requiring perseverance. Together, these results provide support for the idea that grit exhibits state-like tendencies, and that encouraging individuals to reflect on failures may result in improved behavioural outcomes.     

Reinforcer choice as an antecedent versus consequence

Four children with autism received opportunities to choose among several preferred stimuli either immediately before or after task responding. The response requirement for reinforcement systematically increased within each session. Two children engaged in higher levels of responding when reinforcement choice was provided as an antecedent to task completion, and 3 of the 4 children showed a preference for the antecedent choice condition.     

An evaluation of antecedent exercise on behavior maintained by automatic reinforcement using a three-component multiple schedule

We evaluated antecedent exercise for treating the automatically reinforced problem behavior of 4 individuals with autism. We conducted preference assessments to identify leisure and exercise items that were associated with high levels of engagement and low levels of problem behavior. Next, we conducted three 3-component multiple-schedule sequences: an antecedent-exercise test sequence, a noncontingent leisure-item control sequence, and a social-interaction control sequence. Within each sequence, we used a 3-component multiple schedule to evaluate preintervention, intervention, and postintervention effects. Problem behavior decreased during the postintervention component relative to the preintervention component for 3 of the 4 participants during the exercise-item assessment; however, the effects could not be attributed solely to exercise for 1 of these participants.
