In CA1 neurons of guinea pig hippocampal slices, long-term potentiation (LTP) was induced in field excitatory postsynaptic potentials (EPSPs) or population spikes (PSs) by the delivery of high-frequency stimulation (HFS, 100 pulses at 100 Hz) to CA1 synapses, and was reversed by the delivery of a train of low-frequency stimulation (LFS, 1000…

If a target stimulus is presented together with a response-irrelevant distractor stimulus, both stimuli can be encoded together with the response in an event file (see Hommel, 2004). The repetition of any feature of such an event-file can then retrieve the previously encoded response. This kind of feature-based retrieval is an important mechanism…

The evaluative conditioning (EC) phenomenon is central to the study of preference acquisition and attitude formation. Early studies have reported EC in the absence of awareness, but more recent work has questioned this conclusion. In previous work, using briefly presented and pattern-masked conditioned stimuli (CSs), we found that above-chance…

The collection of articles presented by Pollak, Camras, and Cole (2019) provides a stimulating survey of the current state of research on emotional development. However, the special issue also makes apparent the need for defining the construct of interest. Definitions of emotions guide how researchers deal with fundamental theoretical and…

Two themes emerge from studies of the development of symbolic understanding; that development proceeds through multiple levels of understanding prior to full and reflective knowledge of the representational function of pictorial symbols, and that development is founded upon individual cognitive and social cognitive proclivities as well as on…

Creativity is a fundamental human accomplishment from scientific advances to composing music. The left dorsolateral prefrontal cortex (DLPFC) and inferior frontal gyrus (IFG) are important metacontrol hubs in flexibility and persistence brain states, respectively. Those hubs are related to divergent thinking, insight problem-solving, and…

It is a prevailing theoretical claim that path integration is the primary means of developing global spatial representations. However, this claim is at odds with reported difficulty to develop global spatial representations of a multiscale environment using path integration. The current study tested a new hypothesis that locally similar but…

Uncertainty tolerance, individuals' perceptions/responses to uncertain stimuli, is increasingly recognized as critical to effective healthcare practice. While the COVID-19 pandemic generated collective uncertainty, healthcare-related uncertainty is omnipresent. Correspondingly, there is increasing focus on uncertainty tolerance as a health…

Objective: This study sought to examine if hypervigilance is one mechanism through which aspects of less supportive campus climates are associated with mental health symptoms for college students. Participants: Data from 386 undergraduate college students attending a small college in the northeastern United States were collected. Methods:…

Self-determination skills are critical for improving life outcomes for individuals with intellectual or developmental disabilities (IDD). The recent growth of postsecondary education (PSE) programs for those with IDD has provided additional opportunities for teaching self-determination skills. This study used a multiple probe across participants…

This paper analyses the opportunities for presenting knowledge that are created when assessment allows senior high school biology students to draw on linguistic and visual resources when constructing meaning in response to short-answer examination-style questions requiring a sequential explanation. Students within one senior high school biology…

This study replicates Felser and Roberts (2007), which used a cross-modal picture priming task to examine indirect-object dependency processing in classroom L2 learners. The replication focuses on early L2 learners with extensive naturalistic L2 exposure (n = 22)--an understudied group in the literature--and investigates whether these learners, in…

This article explores the use of visual tools--maps, diagrams, graphic organizers, and illustrations that link two or more ideas together in a conceptual manner--and how they are commonly used in deaf education. Visual tools improve the quantity and quality of learning in language, science, and mathematics across all ages and all groups of deaf…

Older adults show a progressive cognitive decline, and although language processing appears to resist advancing age, studies in word retrieval report that elders show important difficulties. Previous research reports that such failures increase from age 70 years, which suggests that during the fourth age word retrieval would exhibit even stronger…

Children with autism spectrum disorder often demonstrate difficulty communicating with others, and this may affect the extent to which they can engage in contextually appropriate language during play. This study examined the effects of a social script-training intervention using generic picture cues on the number of contextually appropriate play…
