Revisiting Alpha Resting State Dynamics Underlying Hallucinatory Vulnerability:...
Honcamp, Hanna; Schwartze, Michael; Amorim, Maria; Linden, David; Pinheiro, Ana P.; Kotz, SonjaResting state (RS) brain activity is inherently non-stationary. Hidden Semi-Markov Models (HsMM) can characterize the continuous RS data as a sequence of recurring and distinct brain states along with their spatio-temporal dynamics. Recent explorations suggest that EEG brain state dynamics in the alpha frequency link to auditory hallucination proneness (HP) in nonclinical individuals. The present study aims to ...
Attention and emotion shape self-voice prioritization in speech processing
Pinheiro, Ana P.; Sarzedas, João; Roberto, Magda Sofia; Kotz, SonjaBoth self-voice and emotional speech are salient signals that are prioritized in perception. Surprisingly, self-voice perception has been investigated to a lesser extent than the selfface. Therefore, it remains to be clarified whether self-voice prioritization is boosted by emotion, and whether self-relevance and emotion interact differently when attention is focused on who is speaking vs. what is being said. T...
Blindness influences emotional authenticity perception in voices: Behavioral an...
Sarzedas, João; Lima, César F.; Roberto, Magda Sofia; Scott, Sophie K; Pinheiro, Ana P.; Conde, TatianaThe ability to distinguish spontaneous from volitional emotional expressions is an important social skill. How do blind individuals perceive emotional authenticity? Unlike sighted individuals, they cannot rely on facial and body language cues, relying instead on vocal cues alone. Here, we combined behavioral and ERP measures to investigate authenticity perception in laughter and crying in individuals with early...
From sound perception to automatic detection of schizophrenia: an EEG-based dee...
Barros, Carla Isabel Dias; Roach, Brian; Ford, Judith M.; Pinheiro, Ana P.; Silva, Carlos A.Deep learning techniques have been applied to electroencephalogram (EEG) signals, with promising applications in the field of psychiatry. Schizophrenia is one of the most disabling neuropsychiatric disorders, often characterized by the presence of auditory hallucinations. Auditory processing impairments have been studied using EEG-derived event-related potentials and have been associated with clinical symptoms ...
Is second best good enough? An EEG study on the effects of word expectancy in s...
Frade, Sofia; Pinheiro, Ana P.; Santi, Andreia; Raposo, AnaSentence comprehension can be facilitated when readers anticipate the upcoming word. Notwithstanding, it remains uncertain if only the most expected word is anticipated, as postulated by the serial graded hypothesis, or if all probable words are pre-activated, as proposed by the parallel probabilistic hypothesis. To test these contrasting accounts, we compared the processing of expected and unexpected words wit...
The time course of emotional authenticity detection in nonverbal vocalizations
Magro, Tatiana; Correia, Ana Isabel; Roberto, Magda Sofia; Scott, Sophie K; Lima, César F.; Pinheiro, Ana P.Previous research has documented perceptual and brain differences between spontaneous and volitional emotional vocalizations. However, the time course of emotional authenticity processing remains unclear. We used event-related potentials (ERPs) to address this question, and we focused on the processing of laughter and crying. We additionally tested whether the neural encoding of authenticity is influenced by at...
Stimuli in 3 Acts: A normative study on action-statements, action videos and ob...
Cipriano, M.; Carneiro, Paula; Albuquerque, Pedro B.; Pinheiro, Ana P.; Lindner, IsabelThe study of action observation and imagery, separately and combined, is expanding in diverse research areas (e.g., sports psychology, neurosciences), making clear the need for action-related stimuli (i.e., action statements, videos, and pictures). Although several databases of object and action pictures are available, norms on action videos are scarce. In this study, we validated a set of 60 object-related eve...

Examining the effects of emotional valence and arousal on source memory: A meta...
Pereira, Diana R.; Teixeira-Santos, A.C.; Sampaio, Adriana; Pinheiro, Ana P.The current meta-analysis examined the effects of valence and arousal on source memory accuracy, including the identification of variables that moderate the magnitude and direction of those effects. Fifty-three studies, comprising 85 individual experiments (N = 3,040 participants), were selected. Three separate analyses focusing on valence effects (valence-based: negative-neutral; positive-neutral; negative-pos...
Associations between music training and cognitive abilities: The special case o...
Vincenzi, Margherita; Correia, Ana Isabel; Vanzella, Patricia; Pinheiro, Ana P.; Lima, César F.; Schellenberg, GlennWe sought to clarify the commonly accepted link between music training and cognitive ability. Professional musicians, nonprofessionals with music training, and musically untrained individuals (N = 642) completed measures of musical ability, personality, and general cognitive ability. Professional musicians scored highest on objective and self-report measures of musical ability. On personality measures, professi...
