Measuring Perceptual Consciousness, Marjan Persuh
Publications and Research
Conscious perception is typically assessed with either objective or subjective measures (Seth et al.,2008). Measures are considered objective if conscious perception is estimated from performancein a discrimination task; inability to discriminate between stimuli is taken as evidence thatparticipants had no conscious perception (Hannula et al., 2005). Measures are considered subjectiveif participants report their visual experience on each trial (Sergent and Dehaene, 2004; Del Culet al., 2007). One type of subjective measures consists of metacognitivejudgments; the relationshipbetween metacognition and perceptual awareness is a matter ofdebate (Fleming and Lau, 2014;Jachs et al., 2015) and I will not discuss these measures further. Likewise, …

Objectives: This study investigated the effects of sleep deprivation on perception of task difficulty and use of heuristics (mental shortcuts) compared to naturally-experienced sleep at home. Methods: Undergraduate students were screened and assigned through block-random assignment to Naturally-Experienced Sleep (NES; n=19) or Total Sleep Deprivation (TSD; n=20). The next morning, reported fatigue, perception of task difficulty, and use of “what-is-beautiful-is-good,” “greedy algorithm,” and “speed-accuracy trade-off ” heuristics were assessed. Results: NES slept for an average of 354.74 minutes (SD=72.84), or 5.91 hours. TSD rated a reading task as significantly more difficult and requiring more time than NES. TSD was …

Increasing numbers of Hispanic immigrants are entering the US and learning American–English (AE) as a second–language (L2). Previous studies investigating the relationship between AE and Spanish vowels have revealed an advantage for early L2 learners for their accuracy of L2 vowel perception. Replicating and extending such previous research, this study examined the patterns with which early and late Spanish–English bilingual adults assimilated naturally-produced AE vowels to their native vowel-inventory and the accuracy with which they discriminated the vowels. Twelve early Spanish–English bilingual, 12 late Spanish–English bilingual, and 10 monolingual listeners performed perceptual-assimilation and categorical-discrimination tasks involving AE /i,ɪ,ɛ,ʌ,æ,ɑ,o/. Early bilinguals …
