Perception and perceptual memory play crucial roles in fear generalization, yet their dynamic interaction remains understudied. This research (N = 80) explored their relationship through a classical differential conditioning experiment. Results revealed that while fear context perception fluctuates over time with a drift effect, perceptual memory…

A major question for the study of learning and memory is how to tailor learning experiences to promote knowledge that generalizes to new situations. In two experiments, we used category learning as a representative domain to test two factors thought to influence the acquisition of conceptual knowledge: the number of training examples (set size)…

The present study evaluates the updating of long-term memory for duration. After learning a temporal discrimination associating one lever with a standard duration (4 sec) and another lever with both a shorter (1-sec) and a longer (16-sec) duration, rats underwent a single session for learning a new standard duration. The temporal generalization…

Ambridge argues that there is widespread agreement among child language researchers that learners store linguistic abstractions. In this commentary the authors first argue that this assumption is incorrect; anti-representationalist/exemplar views are pervasive in theories of child language. Next, the authors outline what has been learned from this…

Distinguishing threatening from nonthreatening stimuli is essential for survival and stimulus generalization is a hallmark of anxiety disorders. While auditory threat learning produces long-lasting plasticity in primary auditory cortex (Au1), it is not clear whether such Au1 plasticity regulates memory specificity or generalization. We used…

Animal studies suggest that time delay between acquisition and retrieval of contextual anxiety increases generalization. Moreover, such generalization is prevented by preexposure to the context (CTX), presumably due to an improved representation of such context. We investigated whether preexposure and time-passing modulate generalization of…

The general purpose of this study is to increase, in a classroom environment, formal communication by using reading and writing. Our research focuses on reading as a means to develop the writing of a good précis, which in its turn contributes to improve: 1) memory, vocabulary and grammatical-syntactical structures, in brief, the organization of a…

Despite many years of investigation into implicit learning in nonlinguistic domains, the potential for implicit learning to deliver the kinds of generalizations that underlie natural language competence remains unclear. In a series of experiments, we investigated implicit learning of the semantic preferences of novel verbs, specifically, whether…

Throughout the animal kingdom, the inhibitory neurotransmitter ?-aminobutyric acid (GABA) is a key modulator of physiological processes including learning. With respect to associative learning, the exact time in which GABA interferes with the molecular events of learning has not yet been clearly defined. To address this issue, we used two…

In this article, we present a perspective on the role of the hippocampal system in generalization, instantiated in a computational model called REMERGE (recurrency and episodic memory results in generalization). We expose a fundamental, but neglected, tension between prevailing computational theories that emphasize the function of the hippocampus…

A reminding-based generalization view of category learning was studied in 4 experiments involving a total of 247 college students. Experiments demonstrated that categorization by reminding can affect what is learned about the category and later categorization performance. Implications of the results for category learning are discussed. (SLD)

The effect of general and specific cues on learning information from graphs is analyzed. The study shows that the use of cues influenced the amount of information learned, with variations according to type and placement of cues. (JMF)

Researchers have regarded inductive reasoning as one of the seven primary mental abilities that account for human intelligent behaviours. Researchers have also shown that inductive reasoning ability is one of the best predictors for academic performance. Modelling of inductive reasoning is therefore an important issue for providing adaptivity in…

Notes young children's fast mapping ability for word and fact learning. Finds children's extension of a new word to novel objects from same category but lack of extension for new facts, as replicated by Waxman and Booth, unsurprising. Poses more interesting question: is word learning done solely through more general cognitive systems or through…

A series of pilot experiments were carried out to investigate the influence of stress induced by load and interference on the acquisition and retention of a path finding skill, and to investigate the relationship between two path finding strategies--retention of strings of instructions and understanding of global relationships--as components of…
