Despite a long history of vigilance research, the role of global and local feature discrimination in vigilance tasks has been relatively neglected. In this experiment participants performed a sustained attention task requiring either global or local shape stimuli discrimination. Reaction time to local feature discriminations was characterized by a…

Two studies are reported comparing the performance of monolingual and bilingual children on tasks requiring different levels of working memory. In the first study, 56 5-year-olds performed a Simon-type task that manipulated working memory demands by comparing conditions based on two rules and four rules and manipulated conflict resolution demands…

Adults' and 8-year-old children's perception of emotional faces is disrupted when faces are presented in the context of incongruent body postures (e.g., when a sad face is displayed on a fearful body) if the two emotions are highly similar (e.g., sad/fear) but not if they are highly dissimilar (e.g., sad/happy). The current research investigated…

We represent events as composed of participants. In "Joan was eating lasagna in the lecture hall," for example, this eating event is "partitioned" into participants, including at least Joan, the lasagna, and the lecture hall. In this dissertation, I address two questions about events and the participants that populate them:…

In this dissertation, the robustness of the relationship between the lexical frequency of phonotactic patterns and word-acceptability is examined for words of Amharic, an understudied Semitic language. The patterns under investigation span the whole verb root and include both under-represented and over-represented consonant distributions in the…

In learning contexts, people need to make realistic confidence judgments about their memory performance. The present study investigated whether second-order judgments of first-order confidence judgments could help people improve their confidence judgments of semantic memory information. Furthermore, we assessed whether different personality and…

School connectedness has a significant impact on adolescent outcomes, including reducing risk-taking behavior. This paper critically examines the literature on school-based programs targeting increased connectedness for reductions in risk taking. Fourteen articles describing seven different school-based programs were reviewed. Programs drew on a…

We newly propose that the vigilance decrement occurs because the cognitive control system fails to maintain active the goal of the vigilance task over prolonged periods of time (goal habituation). Further, we hypothesized that momentarily deactivating this goal (via a switch in tasks) would prevent the activation level of the vigilance goal from…

Rats were able to search multiple food cups in a foraging task and successfully return to a fixed, but not a variable, start location. Reducing the number of food cups to be searched resulted in an improvement in performance in the variable start condition. Performance was better when only one or two food cups had to be visited but was still…

In Higher Education, feedback is still largely implemented as an external teacher-centred practice, which has been found to be irrelevant in improving students' language learning. This paper advocates that internal, or self-generated feedback, has a potential role to play in learners' formative processes under the condition that it is implemented…

The current study investigated first language (L1) effects on listener judgment of comprehensibility and accentedness in second language (L2) speech. The participants were 45 university-level adult speakers of English from three L1 backgrounds (Chinese, Hindi, Farsi), performing a picture narrative task. Ten native English listeners used…

The decision to intentionally withhold truthful information, or deception, is a key component of moral development and may be a precursor to more serious anti-social tendencies. Two factors, executive function (EF) and temperamental fear are each thought to influence childhood deception. Few studies, however, have explored deception in relation to…

This study investigated listening strategies used by students in different listening tasks and situations in an English as a foreign language (EFL) context. Thirty EFL students in a university in Vietnam were recruited for the study. The study aimed to explore what listening strategies EFL Vietnamese learners at university level used and why and…

The aim of this study is to explore the task and ego oriented goals of the students majoring at the Faculty of Sports Sciences at Ataturk University. For data collection, "The Task and Ego Orientation in Sport Questionnaire", which was developed by Duda (1) and adapted into Turkish by Toros and Yetim (2), was used in the current study to…

Linear functions are an important part of the middle school mathematics curriculum. Students in the middle grades gain fluency by working with linear functions in a variety of representations (NCTM 2001). Presented in this article is an activity that was used with five eighth-grade classes at three different schools. The activity contains 15 cards…
