Previous evidence indicates that bilinguals are slowed when an unexpected language switch occurs when they are reading aloud. This anticipation effect was investigated using a picture-word translation task to compare English monolinguals and Spanish-English bilinguals functioning in “monolingual mode.” Monolinguals and half of the bilinguals drew pictures or wrote English words for picture or English word stimuli; the remaining bilinguals drew pictures or wrote Spanish words for picture or Spanish word stimuli. Production onset latency was longer in cross-modality translation than within-modality copying, and the increments were equivalent between groups across stimulus and production modalities. Assessed within participants, bilinguals were slower than monolinguals under intermixed but not under blocked trial conditions. Results indicate that the bilingual anticipation effect is not specific to language-mixing tasks. More generally, stimulus-processing uncertainty prevents establishment of a “base” symbolic-system procedure (concerning recognition, production, and intervening translation) and the inhibition of others. When this uncertainty is removed, bilinguals exhibit functional equivalence to monolinguals.

One major class of evidence indicating that associative processes contribute significantly to the development of morphine tolerance is based on the context specificity of the phenomenon: Changing the stimulus context correlated with drug administration diminishes tolerance. If this outcome is analogous to stimulus generalization decrement in traditional learning studies, then the flattening of generalization gradients over time may modulate the traditional test for tolerance. Accordingly, the effect of retention interval on context specificity of tolerance in rats was investigated. A hot-plate pain sensitivity test indicated that a context shift disrupted tolerance after a short, but not a long, retention interval. Methodological implications for assessment of learning processes in tolerance are noted.

This study investigated whether a prior context influenced lexical access as indexed by participants' electrophysiological response in the N1 from 132 to 192 ms poststimulus. Ambiguous, high-frequency (HF), and low-frequency (LF) words were presented in neutral and biasing contexts. Event-related potentials (ERPs) for ambiguous words were compared with those for unambiguous HF (word form) and LF (word meaning) control words. Word frequency effects in the N1 extended previous ERP findings. A marginal effect of context for LF words provided electrophysiological support for the context-by-frequency interaction shown in reaction time paradigms. In neutral context, responses to ambiguous words were comparable to responses to HF words, and in biasing context (where context instantiated the subordinate sense), responses to ambiguous words were comparable to responses to LF words. The results establish temporal parameters for the early operation of context in lexical access. These constraints are more consistent with an interactive than a modular account.

It has been said that the imagination is a powerful tool. We show here that, in reality, this claim may be more than simply a metaphor. Recent studies have revealed that items near the hands benefit from enhanced visual analysis (Abrams, Davoli, Du, Knapp, & Pauli, 2008; Reed, Grubb, & Steele, 2006; Schendel & Robertson, 2004). These results are thought to reflect the importance of representing objects and events that are in close proximity to the body, such as objects that are soon to be grasped or those that must be avoided. Quite naturally, all previous studies that have found perceptual enhancement near the hands have had subjects assume a posture in which their hands were placed close to a visual display. We show here for the first time that the same benefits can occur when one simply imagines such postures.

Viewers were presented with a rapid sequence of very brief stimulus pairs, each of which consisted of a pictured object followed by a related or unrelated word. The form of relatedness between the picture and word was manipulated across experiments (identical concept, associated concept, ink color of the picture). Recognition memory for the pictures was affected not only by whether or not paired items were conceptually identical or semantically related, but also by whether or not the words named an irrelevant feature, ink color. These results show that sequential items are integrated on the basis of similarity at whatever level is available, so that the stability of the memory representation of one or both items is increased. We propose that a common mechanism may underlie integration, priming, and selective attention.

Four European starlings ( Sturnus vulgaris) discriminated a 300-ms segment of starling song from a 300-ms segment of budgerigar song in three contexts in a two-choice key-peck operant discrimination task. In the starling-song context, on each trial, one of the song segments was presented in the context of starling song; in the budgerigar-song context, the segments were presented in the context of budgerigar song. In the no-song context, the song segments were presented outside of a song context. On occasional unreinforced probe trials, the song segments were replaced by either white noise or silence. On noise trials in the two song contexts, but not on silent trials in the song contexts or noise trials in the no-song context, the starlings were significantly more likely to respond to the key associated with the starling song segment than to the key associated with the budgerigar song segment. This effect was especially pronounced in the starling-song context. The results indicate that noise induces perceptual restoration of missing birdsong segments in songbirds.

This study demonstrates that a perceptual illusion that alters the perceived length of two lines also affects spatial attention. We used a cuing method that was introduced to study space- versus object-based attention. Two parallel lines of equal length were placed so that the distance between them was equal to the length of the lines. We then added a scene with depth cues to produce a strong illusion that one line was longer than the other. The results showed that spatial attention is distributed in space as it is perceived and altered by perceptual organization. These data have implications for assumptions concerning the spatial medium that guides attention and the role of depth and distance cues in spatial orienting, as well as for understanding attentional systems related to neuropsychological functions that respond to space and objects.

How has the COVID-19 pandemic affected intimate relationships? The existing literature is mixed on the effect of major external stressors on couple relationships, and little is known about the early experience of crises. The current study used 654 individuals involved in a relationship who provided data immediately before the onset of the pandemic (December, 2019) and twice during the early stages of the pandemic (March and April, 2020). Results indicate that relationship satisfaction and causal attributions did not change over time, but responsibility attributions decreased on average. Changes in relationship outcomes were not moderated by demographic characteristics or negative repercussions of the pandemic. There were small moderation effects of relationship coping and conflict during the pandemic, revealing that satisfaction increased and maladaptive attributions decreased in couples with more positive functioning, and satisfaction decreased and maladaptive attributions increased in couples with lower functioning.
