Stress disrupts context-dependent memory.
Memory is facilitated when the retrieval context resembles the learning context. The brain structures underlying contextual influences on memory are susceptible to stress. Whether stress interferes with context-dependent memory is still unknown. We exposed healthy adults to stress or a control procedure before they learned an object-location task in a room scented with vanilla. Memory was teste...
متن کاملStress disrupts response memory retrieval.
Stress effects on memory are well-known. Most studies, however, focused on the impact of stress on hippocampus-dependent 'declarative' memory processes. Less is known about whether stress influences also striatum-based memory processes, such as stimulus-response (S-R) memory. First evidence from rodent experiments shows that glucocorticoid stress hormones may enhance the consolidation of S-R me...
متن کاملEnvironmental Context—Dependent Memory
The impact on recall of reinstatement or change of the environment existing at the time of learning is reviewed. While strong and stable effects have been observed for recall, effects on recognition rarely occur because the word itself is a powerful cue (the outshining hypothesis). A classification of context effects is presented and the conditions where such effects are likely to be maximized ...
متن کاملInducible repression of CREB function disrupts amygdala-dependent memory.
Evidence from Aplysia, Drosophila, mice, and rats indicates that the CREB (cAMP/Ca2+ responsive element binding protein) family of transcription factors is critical for long-term memory. Recent findings, however, suggest that performance abnormalities may contribute to the memory deficits attributed to CREB manipulations in mammals. To clarify the role of CREB in memory, we used a paradigm, con...
متن کاملExploring the mechanism of context-dependent memory
Many experiments within the memory literature show evidence for context-dependent effects in memory (Gieselman & Bjork, 1980; Godden & Baddeley, 1980; Marian & Neisser, 2000; Smith, 1986; Smith & Vela, 2001). There have also been a number of failed replications of this effect (Farnsworth, 1930; Reed, 1931; Smith, Glenberg, & Bjork, 1978; Godden & Baddeley, 1980; Jacoby, 1983). If the context-de...
